High-temperature calcined alumina powder products have a high melting point, excellent mechanical strength, hardness, high resistivity, and thermal conductivity. They are widely applicable in industries such as electronic equipment, structural ceramics, refractory materials, wear-resistant materials, and polishing materials.

Alumina powder has a white, fine particle appearance with uniform particle size, low water absorption, and stable chemical properties. It is easily soluble and has strong fluorine absorption, suitable for producing aluminum metal via salt electrolysis and for manufacturing corundum, ceramics, refractory products, and other alumina chemical products. High purity ultra-fine alumina powder with purity levels of 99.99% and 99.999% features good activity, high purity, concentrated particle size distribution, and sulfur-free content. It is widely used in applications such as trichromatic phosphor, YAG single crystal, synthetic gemstones, high-pressure sodium lamps, and long-lasting phosphor matrices, as well as in high-tech fields like structural ceramics, bio-ceramics, and functional ceramics. It is one of the materials in the new materials of the 21st century.

Alumina powder is produced using top-grade industrial alumina, aluminum hydroxide, and additive technology. After phase conversion calcination, it is further processed using advanced powder grinding technology and techniques. The resulting active alumina micro-powder boasts high activity, fine particle size; high purity, high melting point, good thermal stability, high true specific gravity, low shrinkage, high hardness, excellent electrical insulation properties, good wear resistance, impact resistance, and resistance to acids, alkalis, and corrosion.
