AI Fuels MLCC Market Growth; Breakthroughs in Barium Titanate Powder Spray Dryers Boost Rapid Domestic SubstitutionMarket Opportunities and Challenges of Barium Titanate Powder Amid the AI Boom
As AI technology penetrates 5G communications, IoT, automotive electronics and other sectors, demand for MLCCs, known as the "industrial staple", has exploded. Statistics show that premium 5G smartphones consume more MLCCs than their 4G counterparts, while new energy vehicles use five times as many MLCCs as conventional fuel cars in power systems, ranging from 2,000 to 2,500 pieces. The global MLCC market size is expected to exceed 149 billion RMB by 2025. As the world’s largest consumer market accounting for 45% of global demand, China boasts huge potential for domestic substitution.
As the core dielectric raw material of MLCCs, barium titanate (BaTiO₃) directly determines the dielectric constant, reliability and miniaturization potential of MLCCs. High-purity nano-sized barium titanate powder has become the mainstream market product. After sintering, it forms dense sintered bodies that enhance ceramic toughness and strength while lowering sintering temperatures. Nevertheless, the global high-end barium titanate powder market has long been monopolized by enterprises including Japan’s Sakai Chemical and U.S.-based Ferro. Domestic leading firm Sinocera holds merely 10% market share, making domestic substitution of high-performance powder an urgent priority.
Core Bottlenecks Restricting Domestic Production of Barium Titanate MLCC Powder
Liquid-phase methods (hydrothermal synthesis, sol-gel method, etc.) dominate the preparation of barium titanate MLCC powder. Grinding and drying are core processes governing powder quality, yet they are plagued by four major technical bottlenecks:
(1) Pain Points in the Grinding Stage
Severe particle agglomeration: Nano barium titanate has a large specific surface area, and van der Waals forces readily trigger hard agglomeration during grinding, worsening powder flowability and increasing porosity of sintered ceramics.
Uneven particle size distribution: Fluctuations in the rotational speed and media ratio of traditional sand mills widen the particle size span factor (ideal value < 1.2), resulting in inconsistent dielectric performance of MLCCs.
Risk of impurity contamination: Wear of grinding media and equipment surfaces easily introduces metallic impurities. Excess Fe²⁺, for instance, will degrade the insulation performance of MLCCs.
Conflict between energy consumption and efficiency: Conventional equipment requires over 8 hours of grinding to reach D50 = 100 nm, consuming massive energy and risking crystal phase transformation of barium titanate, which reduces its dielectric constant.
(2) Challenges in the Drying Stage
Thermal susceptibility defects: Barium titanate tends to undergo crystal transformation when drying temperature exceeds 200 °C, leading to higher dielectric loss.
Poor particle size control: Standard spray dryers feature a wide droplet size distribution (±10%), resulting in uneven powder particle sizes after drying and impairing uniformity during MLCC lamination molding.
Wall adhesion and contamination: Wet powder sticks to tower walls and forms secondary agglomerates. If the equipment is made of ordinary stainless steel, the leaching rate of Fe and Ni ions can reach 0.05%, lowering powder purity.
Insufficient sphericity: Traditional processes fail to achieve high spherical granulation (sphericity < 70%), leading to sintered MLCC compactness below 95% and unstable electrical performance.
Longxin Intelligent Full-Chain Solution: Disruptive Innovation Covering Grinding to Drying
To address the above pain points, Longxin Intelligent launches an integrated solution combining turbine pin-type nano dual-power sand mill and centrifugal airflow multi-purpose spray dryer, enabling precise full-process control.

Tap into the Big Health Market: Oligosaccharide Spray Dryers Usher in a New Era of High-Quality Functional SugarsOligosaccharides: The Golden Ingredient for Functional Foods Amid the Big Health Boom
As guardians of intestinal health, functional oligosaccharides keep unlocking massive market potential thanks to their unique physiological functions and application strengths. Among them, Isomaltooligosaccharide (IMO) ranks as the most widely produced and applied functional oligosaccharide, dominating the industry with four core advantages:
Low sweetness with no health burdens to meet wellness demands
It delivers only 30%–50% of sucrose’s sweetness with a mild, non-cloying taste. It can partially replace sucrose in low-sugar and low-calorie foods, eliminating health risks brought by traditional high-sugar diets.
Anti-cavity oral protection suitable for all age groups
It cannot be broken down by oral bacteria to produce acid that erodes tooth enamel. Widely used in children’s snacks and elderly food, it addresses the cavity risks of conventional candies and baked goods.
High tolerance for broad application coverage
Most consumers will not suffer bloating or diarrhea after intake. It avoids sharp blood sugar spikes for diabetics and serves as a dairy substitute for lactose-intolerant people, catering to all age brackets.
Excellent thermal and acid stability to break process limitations
It boasts outstanding resistance to heat and acid. Its molecular structure remains intact during high-temperature baking and acidic beverage production at pH 2–12 without losing functional activity. Compatible with baking, sterilization and long-term storage, it offers food manufacturers greater room for formula innovation.
Surging Market Demand for Functional Oligosaccharides
Market demand for functional oligosaccharides is exploding. Industry statistics show the global market registers an annual growth rate well above average. As the world’s largest producer and consumer, China’s market size exceeded 8 billion RMB in 2024.
Application boundaries have expanded beyond traditional dairy and beverages to infant formula, health supplements and pharmaceutical excipients. For instance, Galactooligosaccharide (GOS) is added to infant milk powder to mimic the prebiotic benefits of breast milk; isomaltooligosaccharide acts as the core raw material for intestinal regulators in health products. Such applications raise stricter standards for oligosaccharide powder: high purity, fine particle size and zero impurities. The technical performance of spray drying equipment directly determines whether manufacturers can seize market opportunities.
Prominent Industry Pain Points: Four Core Challenges of Conventional Oligosaccharide Spray Dryers
Despite bright market prospects, traditional spray drying equipment suffers poor material adaptability, a major bottleneck restricting high-quality industrial development. Given oligosaccharide syrup’s high viscosity and strong hygroscopicity, conventional centrifugal spray dryers face four critical drawbacks:
Severe tower wall buildup leading to heavy material loss and safety hazards
High viscosity and surface tension cause atomized syrup droplets to stick to the tower inner wall, forming agglomerated powder deposits. Long-term high-temperature baking darkens and scorches the deposits. Factories must halt production every shift to clean wall buildup, then re-dissolve, concentrate and re-dry recovered materials. This pushes up labor time and energy consumption. Worse, incomplete cleaning may mix burnt particles into finished powder, forming black specks that compromise purity and food safety.
Inadequate drying leading to excessive moisture content
Conventional drying towers often feature insufficient effective volume or underpowered heating systems, failing to fully dry atomized droplets inside the tower. For example, a centrifugal spray dryer designed to produce powder with 95% dry matter often yields products exceeding moisture standards. Extra post-drying procedures cut production efficiency and risk damaging oligosaccharide functionality via secondary heating.
Flawed structural design exacerbating process defects
Many towers suffer oversized cone angles and poorly configured air outlets. Overly large cones shorten material residence time, preventing full contact with hot airflow; ill-designed outlets create turbulent air and uneven droplet distribution, worsening wall adhesion and incomplete drying.
Poor atomization resulting in inconsistent particle size
Unstable atomization and overlong spray distances of traditional centrifugal atomizers produce droplets with drastically varying diameters (some exceeding 200 μm). Tiny droplets are swept away by hot air as dust loss, while oversized droplets retain excess moisture and form wet powder. The final product features uneven particle size and poor flowability, complicating subsequent packaging and application.
These issues translate into low output, high energy consumption and high reject rates. They also fail downstream clients’ requirements for high-purity, high-activity and stable oligosaccharide powder, becoming a stumbling block for manufacturers competing in the big health market.
Against the backdrop of the in-depth implementation of the Healthy China 2030 Strategy, functional food stands among the fastest-growing segments of the food industry. Consumers’ rising demand for natural, healthy and functional ingredients drives upgrades across the food additive sector. Functional oligosaccharides such as IMO, Fructooligosaccharide (FOS) and Xylooligosaccharide (XOS), with core prebiotic properties, form a vital link connecting food manufacturing and the big health industry.
Spray drying, the core process converting oligosaccharide syrup into high-purity powder, emerges as the decisive factor governing product quality, production efficiency and market competitiveness. With years of R&D expertise in drying equipment, Longxin Drying has launched an innovative pressure spray dryer tailored to the oligosaccharide industry’s pain points. Groundbreaking technology eliminates traditional process bottlenecks and opens a new chapter of premium production for functional sugars, sugar alcohols and food additives.
Innovation Solves Industrial Difficulties: Technical Breakthroughs of Longxin’s New Pressure Spray Dryer
Drawing on decades of drying equipment R&D experience and the physical properties of oligosaccharide syrup, Longxin Drying has developed the all-new YPG Oligosaccharide-Specific Pressure Spray Dryer. Five core technical innovations eliminate inherent flaws of conventional units and deliver efficient, energy-saving, high-quality production:
Precision Atomization System: Accurate particle control to resolve incomplete drying
Customized for high-viscosity oligosaccharide syrup, the multi-channel pressure atomizer comes with interchangeable ceramic or stainless steel inserts (orifice sizes: 0.5–3.0 mm) and precisely adjustable atomization angles for tight control over average droplet size. Unlike centrifugal atomizers plagued by overlong spray distances and uneven particle distribution, this system instantly boosts droplet specific surface area for full contact with hot air and rapid moisture evaporation. It eliminates incomplete drying and excess moisture, stabilizing dry matter content of finished powder above 95% to meet high-purity standards.
Optimized Drying Tower Structure: Anti-stick design to cut material loss
Two structural breakthroughs address tower wall powder buildup:
Optimized cone angle: Set at 45°, much narrower than the 60°+ cones of traditional equipment, it extends material residence time for thorough drying. The tower body adopts mirror-polished 304 stainless steel to reduce adhesion surfaces and minimize wall deposits.
Upgraded hot air distributor: A 3D stereoscopic hot air distributor delivers uniform wind speed with minimal deviation, generating stable spiral hot airflow to avoid local overheating and burnt powder. Droplets disperse evenly without direct impact on tower walls, fundamentally reducing adhesion.
The tower is also equipped with an air-swept anti-stick system and timed air hammers to clear minor deposits in real time, removing the need for frequent production halts and lowering material loss rates.
Two-Stage Powder Recovery System: Efficient capture to boost output and purity
Conventional single-stage bag dust collectors easily suffer blocked filter bags that reduce airflow and limit throughput. Longxin adopts a dual recovery system combining two-stage cyclone separators and pulse back-blow bag dust collectors for superior powder capture efficiency.
Intelligent Temperature & Feeding System: Stable production compatible with complex processes
To preserve oligosaccharide functionality, multi-mode heating (steam, electric, gas optional) is fitted with a Siemens PLC and advanced PID intelligent algorithm for precise, adjustable inlet air temperature control. Accurate temperature regulation prevents local overheating that causes oligosaccharide hydrolysis or denaturation.
The feeding system uses positive displacement diaphragm pumps with adjustable flow rates of 0.5–20 m³/h, integrated with online viscometers and pressure sensors. It monitors feed viscosity and delivery pressure in real time and automatically adjusts feeding speed to maintain consistent atomization, accommodating oligosaccharide syrups of varying concentrations without repeated parameter tuning.
Energy-Saving & Eco-Friendly Design: Cost reduction and sustainable green production
For energy efficiency, waste heat recovery technology recycles residual heat from exhaust gas to preheat incoming fresh air, cutting overall energy consumption by 10–20% versus traditional dryers. For environmental compliance, an exhaust treatment system combining pulse dust removal and activated carbon adsorption delivers low emission concentrations to meet national environmental standards, supporting manufacturers’ green production targets amid tightening environmental regulations.

Leveraging the Huge Health Market: Oligosaccharide Spray Dryers Usher in a New Era of High-Quality Functional SugarsFueled by the steady implementation of the Healthy China 2030 Strategy and consumption upgrading, the big health industry is witnessing tremendous growth opportunities. As a core segment of the big health sector, functional food has become the key driver for transformation and upgrading within the food manufacturing industry.
Oligosaccharides, a mainstream type of prebiotics widely popular in functional foods, deliver multiple physiological benefits: regulating intestinal flora, boosting immunity, low calorific value and anti-cavity properties. They are rapidly applied in dairy products, beverages, baked goods, health care products, pharmaceuticals and many other fields, accompanied by continuously rising market demand.
However, as the market sets higher standards for oligosaccharide product quality, traditional spray drying processes are confronted with prominent challenges. Especially when converting oligosaccharide syrup into high-purity, high-flowability powder, conventional equipment suffers from multiple technical bottlenecks that greatly limit improvements in product quality and production efficiency.
Three Core Pain Points of Traditional Equipment for Oligosaccharide Spray Drying
Heavy wall adhesion due to high-viscosity oligosaccharide syrup
Oligosaccharides feature complex molecular structures, so atomized syrup droplets remain highly adhesive. If the drying system is poorly designed, droplets will stick to the inner wall of the drying tower, causing material loss, difficult cleaning, and even halts in continuous production.
Inadequate drying and poor moisture control
Many existing devices adopt drying towers with insufficient effective volume or underpowered heating systems. Atomized droplets cannot be fully dried within limited residence time, resulting in finished powder with excessive moisture. This undermines the solubility and flowability of products, and may trigger caking, mildew and other quality hazards, severely impairing performance in downstream end products.
Defective structural design leading to severe powder buildup on tower walls
Problems including excessively large tower cone angles, unreasonable air outlet layout and uneven hot air distribution create turbulent airflow. Partially dried materials collide with and adhere to the tower wall ahead of schedule. Besides, unsatisfactory atomization or excessive spray distance causes droplets to hit the tower wall before full drying, forming wet powder agglomerates and lowering product yield and purity.
More critically, residual powder left uncleaned will carbonize in high-temperature areas such as the tower top and generate black spots, which directly contaminate finished products and damage product appearance and food safety.
To tackle these common industry-wide hurdles, Longxin Drying relies on technological innovation, conducts in-depth research on the material properties and drying mechanisms of oligosaccharides, and releases the new-generation YPG Pressure Spray Drying & Cooling Unit. Custom-designed for functional sugars, sugar alcohols and food additive manufacturers, this unit fully breaks through the technical bottlenecks of oligosaccharide spray drying.
Innovation as the Core of Progress: Technical Breakthroughs of Longxin Pressure Spray Dryers

Its specific surface area reaches 500–1500 ㎡/kg, greatly accelerating water evaporation and shortening drying time to 15–60 seconds, making it perfectly suitable for heat-sensitive materials.
Dynamic Drying System Optimizing Airflow and Thermal Field Distribution
The self-developed 3D three-dimensional hot air distributor delivers evenly distributed hot air with minimal wind speed deviation. Combined with a drying tower with optimized cone angle, the design eliminates airflow dead zones and avoids material wall adhesion. The tower body is fitted with an automatic air hammer/electric hammer knocking system and a cooling air ring at the lower cone to prevent burnt powder.
Multi-Stage Separation System Boosting Recovery Rate and Purity
A dual-stage powder collection setup consisting of cyclone separators and pulse back-blow bag dust collectors achieves a total material recovery rate of over 95%. The automatic pulse back-blow function clears powder accumulated on filter bags, preventing air volume drop caused by filter blockage and securing long-term stable system operation.
Modular Secondary Treatment Meeting Diversified Production Needs
Clients can optionally install a ZLG vibrating fluidized bed secondary drying system to further reduce powder moisture and improve flowability; or integrate a CIP clean-in-place system to realize automatic cleaning and sterilization, complying with strict hygiene and safety standards.
Intelligent Control System Realizing Full-Process Automation
Adopting Siemens PLC + touch screen control system, it monitors real-time key parameters including inlet/outlet air temperature, feed liquid pressure and tower negative pressure, and supports remote monitoring and data recording.

Against the sweeping AI wave, domestic substitution of MLCCs is accelerating: How Longxin’s barium titanate nano sand mill and intelligent spray drying production line break the bottlenecks restricting the industrialization of electronic ceramic materialsDomestic Substitution of MLCCs Accelerated by AI Boom: Analysis of Market Demand and Trends for Barium Titanate Ceramic Powders
Amid the rapid advancement of artificial intelligence, booming demand for high-performance electronic components has emerged across emerging sectors including 5G communications, the Internet of Things (IoT), and automotive electronics. Known as the "industrial staple", MLCCs (Multi-Layer Ceramic Capacitors) stand as indispensable foundational components in electronic circuits of the AI era, thanks to their high capacitance, stable performance and outstanding reliability. Statistics indicate that high-end 4G smartphones adopt 900–1,100 MLCCs, while the figure rises to 990–1,320 units for premium 5G handsets. New energy vehicles require five times more MLCCs than conventional fuel-powered cars in their power systems, ranging from 2,000 to 2,500 pieces. Driven by the growing penetration of AI terminal devices, the global MLCC market is projected to reach 149 billion RMB by 2025. As the world’s largest MLCC market, China accounts for approximately 45% of global consumption, unlocking enormous room for domestic substitution.
As a pillar material for the electronic ceramics industry, barium titanate (BaTiO₃) serves as the core dielectric raw material for MLCCs, boasting a high dielectric constant, low dielectric loss, and excellent ferroelectric and insulating properties. High-purity nano-scale barium titanate powder has become the mainstream market requirement. After sintering, such powder forms dense sintered bodies with an even particle size distribution, which not only improves the toughness and strength of ceramics but also lowers sintering temperatures to cut energy costs. Nevertheless, the global market for high-end MLCC formulation powder is currently monopolized by Japanese Sakai Chemical and U.S.-based Ferro, with domestic leading manufacturers holding merely around 10% market share. This creates an urgent imperative to realize domestic substitution of high-performance barium titanate powder.
Bottlenecks in Barium Titanate MLCC Ceramic Powder Preparation: Technical Challenges in Grinding and Drying
Two primary routes are adopted for producing barium titanate MLCC ceramic powder: the solid-state method and the liquid-phase method. Liquid-phase approaches (e.g., hydrothermal synthesis, sol-gel method) are preferred for premium MLCC production for their capacity to manufacture high-purity ultrafine powder. Grinding and drying are pivotal stages governing powder quality throughout the production workflow, yet both are plagued by prominent technical hurdles.
(1) Pain Points of Traditional Grinding Processes
Conventional grinding equipment faces universal drawbacks when processing nano-sized barium titanate powder:
Severe particle agglomeration: Nano barium titanate features large specific surface area and high surface energy. Van der Waals forces readily induce hard agglomerates during grinding, impairing powder flowability and undermining subsequent sintering performance.
Uneven particle size distribution: Fluctuations in grinding parameters (rotational speed, grinding media ratio) lead to broad particle size ranges, resulting in inconsistent dielectric properties of finished MLCCs and reduced product yield.
Risk of impurity contamination: Wear of grinding media and equipment surfaces may introduce metallic impurities that degrade powder purity. For high-reliability MLCCs, such impurities compromise insulation performance and even trigger dielectric breakdown.
Conflict between energy consumption and processing efficiency: Attaining ultra-fine particle sizes demands prolonged grinding cycles on traditional sand mills, driving up power consumption. Excessive heat buildup may also alter the crystal structure of barium titanate, lowering its dielectric constant.
(2) Technical Bottlenecks of Drying Processes
Drying barium titanate powder also presents substantial technical obstacles:
Thermal sensitivity issues: Barium titanate is temperature-sensitive. Conventional drying techniques easily cause localized overheating, triggering crystal transformation or compositional deviation and deteriorating dielectric performance.
Poor particle size controllability: Standard spray dryers fail to precisely regulate droplet size and distribution, yielding dried powder with uneven particle dimensions that compromise uniformity during MLCC lamination and forming.
Wall adhesion and contamination: Wet powder sticking to drying tower walls reduces product purity and generates secondary agglomerates, raising downstream processing costs. Improper equipment materials may leach impurities and degrade powder purity.
Insufficient sphericity: Spherical powder elevates packing density and compactness for high-end MLCCs, yet traditional drying technologies cannot produce highly spherical granules, weakening capacitors’ electrical and mechanical properties.

Bid Farewell to Drawbacks of Traditional Water-soluble Fertilizer Granulation & Drying Potassium Humate Spray Drying Tower Ushers in a New Production TrendBrief Analysis on the Feasibility of Superheated Steam Pneumatic Dryer
Most conventional spray granulation dryers for sodium humate adopt air as the drying medium. They suffer from prominent drawbacks including low drying rate and poor thermal efficiency. The sensible heat and latent heat contained in exhaust gas are difficult and costly to recover, involving high technical barriers. For this reason, exhaust gas is directly discharged by most such dryers currently. Industry statistics show that traditional drying processes generally have low thermal efficiency and longer drying cycles, which not only lowers productivity but also causes massive energy waste.
By contrast, the convection dryer using superheated steam as the drying medium can eliminate the above problems. It also features low net energy consumption, high heat and mass transfer efficiency, superior product quality and environmental friendliness. With high specific heat capacity and thermal conductivity, superheated steam delivers a higher heat transfer coefficient than hot air, accelerating the drying process and enabling cyclic heat reuse to improve overall thermal efficiency.
In addition, the steam atmosphere is oxygen-free, which prevents oxidative deterioration of materials. It is particularly applicable to heat-sensitive humic acid substances and keeps the product activity and color stable. The exhaust gas is treated via condensation and recovery, and the recycled water can be reused. The system achieves true zero emission with remarkable environmental benefits.

Process Flow of Multi-stage Fluidized Granulation Spray Dryer
(1) Raw Material Pretreatment
The enzymatically hydrolyzed protein peptide solution undergoes precision filtration, high-efficiency concentration and other pretreatment processes to adjust its concentration, viscosity and other parameters to the optimal standards for spray drying. The treated material is then accurately delivered to the feeding system of the dryer via pipelines.
(2) Hot Air Generation
Ambient air is heated by high-efficiency heaters to form hot air at a specified temperature. The hot air is delivered to the top of the drying tower and the bottom of the fluidized bed respectively, passing through distribution plates to make full contact with materials and fluidize them. It creates the required thermal and airflow conditions for subsequent drying and granulation.
(3) Slurry Atomization
The liquid material in the feeding system is pumped into the drying tower at a precisely controlled pressure by diaphragm pumps and other equipment. Pressure energy is efficiently converted into kinetic energy. The slurry is ejected upward at high speed from the nozzles to form a high-velocity liquid film, which quickly breaks into fine droplets. The droplet size is inversely proportional to the operating pressure, while the production capacity of the nozzle is proportional to the square of the pressure.
(4) Drying and Spheroidization of Droplets
Atomized droplets and hot air work in an optimized mixed flow inside the drying tower. Hot air evenly enters the tower through the top air distributor and forms a stable downward laminar airflow, while droplets are sprayed upward against the hot air stream. Thanks to the large specific surface area of droplets, internal moisture evaporates rapidly under the action of hot air. Driven by surface tension, droplets shrink into spherical shapes and finally solidify into dry spherical particles. The particles gradually settle in the tower and separate efficiently from hot air.
(5) Fluidized Granulation
Fine powder lifted upward by hot airflow inside the fluidized bed collides with falling wet fine particles in the specially designed atomization and granulation zone. Particles grow gradually through physical effects such as coating and adhesion. Mother liquor or binder is accurately conveyed to atomizing nozzles by pressure pumps. After atomization, it evenly coats the surface of fluidized particles or bonds particles together. Through continuous fluidization, coating and drying, particles keep growing until reaching the target particle size.

Collected fine particles fall to the bottom of the separator and are accurately returned to the atomization zone of the tower via rotary valves for recycling as seed crystals. The remaining waste gas containing trace ultrafine particles is further purified by water film dust collectors to achieve harmless treatment. The treated gas that meets emission standards is finally discharged through the chimney in compliance with regulations.
(8) System Monitoring and Control
The advanced electrical system is composed of an electric control cabinet and high-precision on-site temperature sensors installed at air inlets and material outlets.

Empowering High-Quality Alumina Ceramic Components with Longxin's Precision Spray Drying SolutionsIn the field of high-precision ceramics, the quality of the powder directly determines the performance of the components. Longxin Drying, with its self-developed spray drying technology, precisely empowers the production of alumina ceramic powders, providing excellent solutions for the global high-end ceramics market.
Market Demand & Trends: The Rise of High-End Demand
Alumina ceramics, known for their outstanding properties, are widely used in advanced applications such as semiconductors, 5G communications, and new energy vehicles. With the miniaturization of electronic devices, the increase in high-frequency requirements, and the emergence of extreme environmental applications, the market demand for high-purity, high-performance alumina ceramics is growing explosively.
The market is showing clear signs of polarization: On the one hand, traditional industries still require cost-effective ceramics, while on the other hand, there is a rapid growth in demand for alumina powders with purity above 99.9%, nano-alumina, and specific morphological spherical alumina.
In the future, alumina ceramic powders that meet the requirements of high purity, narrow particle size distribution, high sphericity, and low impurity content will become the key factor determining the upper limit of the performance of structural components.
Core Foundation: The Critical Role of Powder Quality in Component Performance
"Powder determines the outcome" — this is the consensus in the ceramics industry. The density, mechanical strength, dielectric performance, and surface finish of alumina ceramic components are directly determined by the micro characteristics of the raw powder:
Particle Size Distribution: A wide distribution will cause uneven shrinkage during sintering, resulting in internal stress or cracking. Narrow distribution, with ultra-fine powder, promotes densification and improves strength.
Powder Morphology: Spherical alumina powders have excellent flowability, ensuring smooth high-precision processes such as dry pressing and injection molding.
Purity and Impurity Control: Trace impurities, such as sodium, potassium, and iron, can significantly degrade insulation properties and thermal stability, affecting the reliability of high-end applications.
Granulation Powder Performance: High-quality granulated powders possess proper bulk density, good flowability, and sufficient particle strength to ensure uniform and consistent filling during mold formation.
Without high-quality precursor powders, it is impossible to manufacture high-performance alumina ceramic components.
Addressing Pain Points: Bottlenecks and Challenges of Traditional Drying Processes
In the preparation process of alumina ceramic powders, drying and granulation are key stages. However, traditional drying methods are increasingly showing limitations in meeting the rigorous requirements of high-end applications:
Uncontrolled Particle Size Distribution: Traditional atomizer designs are often rough, leading to uneven droplet sizes and broad particle size distribution after drying, making it difficult to meet the uniformity required for high-end sintering.
Thermal Sensitivity Damage: Uneven hot air distribution or local overheating can cause over-baking, agglomeration, or phase transformation, compromising the powder's activity and purity.
Impurity Introduction: The wear of equipment materials or outdated cleaning systems can introduce metal impurities, severely affecting the quality of high-purity alumina.
Low Recovery Rate: For ultra-fine hydrates, boehmite, and nano-alumina, traditional dust removal systems are inefficient, leading to significant raw material loss.
Insufficient Flexibility: General-purpose equipment struggles to provide precise adjustments for different material properties, making it difficult to achieve "one solution for one product."
Longxin’s Solution: Customized Spray Drying Machines Powering Industrial Upgrades
In response to the urgent demand for high-purity, high-performance alumina products, Longxin Drying focuses on customer needs, deeply engaging in the precision ceramic powder sector. We understand that different application areas require various particle sizes, crystal shapes, and purities. Therefore, Longxin has moved away from a one-size-fits-all manufacturing model, offering customized, precision solutions for each product type to ensure high purity and stability from the source.
Whether it is spherical alumina for thermal fillers, ultra-fine alumina for polishing, or boehmite and high-purity alumina for electronic substrates, Longxin can tailor its spray drying processes based on the specific material properties, supporting breakthroughs in industries such as semiconductors and new energy.
