White aluminium oxideis a high-quality alumina powder as raw material, made of fused refining crystal, two alumina content as high as 98.5%, and its slightly higher than the brown corundum hardness, toughness is slightly lower, high purity, self-sharpening is good, grinding ability, heat a small, high efficiency, acid and alkali corrosion, high temperature 1750 degrees Celsius, thermal stability. 
Its abrasive for grinding high-carbon steel, high-speed steel. Can also serve as abrasive polishing materials; precision casting, coating materials, chemical catalyst carrier, special ceramics, grinding wheel, steel, and other advanced refractory. 
White aluminium oxide Physical Performance Indicators:
Project indicators: color pure white; Crystalline trigonal system; Hardness (Mohs) ≥ 9.0; Melting point (℃) 2250; the maximum temperature (℃) 1900; True Density (g/cm3) ≥ 3.90; linear expansion coefficient (0-1600 ℃) 7-9
