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:
