Revolutionize Your Projects With High Quality Alumina Powder

Alumina powder can be found in numerous applications. It serves as an integral raw material in the production of refractories and advanced technical ceramics as well as polishing and abrasive products.
High Purity
Alumina powder is an integral component in many different applications. It is widely utilized in the production of refractory materials like fire bricks, crucibles and furnace linings as well as ceramics and abrasives; furthermore it serves as an excellent catalyst in various chemical reactions; additionally its insulation properties make it essential in electronics manufacturing processes.
High Purity Alumina (HPA) and Ultra High Purity Alumina (UHPA) come in various particle sizes and meshes for your application, and as you increase purity you’ll see greater effectiveness in your use case. UHPA is particularly appreciated in leading-edge technologies where even minute impurities may interfere with performance; HPA market should grow due to increasing LED, semiconductor, and lithium-ion battery demand.
High Hardness
Alumina is an extremely hard and tough material, making it a key component in industrial processes. Plus, its chemically inert nature prevents corrosion under any circumstances – providing stability even under harsh environments.
Due to its thermal resistance and hardness, alumina is widely utilized in the production of microchips and other electronic equipment, as well as being an important ingredient in body armor production and vehicle armor manufacture.
Brown fused alumina powder is used for various abrasive applications, including sandblasting and grinding of metal, glass and ceramic products, as well as as an additive in polymers to improve their mechanical and chemical properties. Furthermore, due to being non-hygroscopic it should be stored in dry environments to prevent moisture absorption; also adhereing to safety guidelines is key when dealing with this material.
High Resistance to Corrosion
Alumina is an inert material, resistant to corrosion in numerous environments and an electrical insulator capable of withstanding high temperatures. Commonly found in refractories and fine ceramics, Alumina comes from natural deposits like native bauxite and laterite deposits sourced by mining operations; once obtained it can be purified or calcined to make it suitable for various uses.
Enhance corrosion resistance by mixing aluminum with other metals to form alloys that are stronger, harder and more durable than pure aluminum.
alumina powder with high thermal conductivity are widely used as fillers in materials like thermal pastes and potting compounds, while in electronics they help disperse heat effectively to prevent overheating or damage to components – essential features for products like electronic devices, lighting products and electric vehicle parts.
High Thermal Conductivity
Alumina is an excellent material for creating machineable components due to its trigonal crystal structure and high density. Depending on its purity level, alumina can possess thermal conductivities up to 30 W/m*K making it one of the top materials used in ceramic thermal management applications.
High durability and wear resistance make ZTA ceramic composites, metal coating, polymer materials and their composites the ideal materials for ZTA coatings, as well as for use as ZTA coatings themselves. Though non-hygroscopic (which means it does not absorb moisture during storage), it should still be stored in an environment without humidity to prevent moisture absorption and protect against agglomeration.
Spherical alumina has long been recognized for its thermal filler properties due to its morphology, low coefficient of thermal expansion and simple preparation process. Consequently, this material is utilized as an effective thermal interface material as well as being utilized in thermally conductive engineering plastics and aluminum-based copper clad boards.
High Resistance to Abrasion
Aluminium oxide powder from our company stands out from traditional sand and grit by having a uniform granular structure and high purity level, which allows it to be used to craft bonded or coated abrasives that have high material removal rates for quicker productivity and shorter processing times.
This grade can be metal-coated for high-temperature brazing assemblies and offers excellent abrasion resistance, chemical stability, electrical insulating properties, dielectric constant, compressive strength and flexural strength – making it suitable for ceramic-to-metal feedthroughs, X-ray equipment and electron tubes.
Calcined alumina powder is produced by heating alumina hydroxide in an electric furnace until its crystal structure has been reduced to its crystal state, producing an exceptional powder with low thermal expansion, excellent performance stability and limited solubility in acids or alkalis.
