White, harder and more frangible than brown aluminum oxide. Good cutting ability and insulativity. Microhardness(Vickers): 1800~2200kg/cm2 .Density: 3.97g/cm3 .Specific heat: 1.1kj/(kg•k) (20~900℃)；Melting point: 2050℃；coefficient of thermal expansion：6.4（20~400℃）；7.6(20~800℃)；Toughness（compression resistance of single particle）：0.72kg。
　　 Main applications: bonded and coated abrasive tools, wet or dry sand blasting; superfine lapping and polishing as well as making high-grade refractory materials. Suitable for processing materials with high hardness and large tensile strength, such as chilled steel, carbon steel, alloy steel , high-speed steel, high carbon steel., Also can be used for polishing piezoelectricity crystal, semiconductor, monocrystalline silicon and polycrystalline silicon. Besides, white aluminum oxide micropowder can be used as insulator, special ceramics and high-grade refractory materials.
