White corundum and white corundum micropowder are made of high-quality alumina powder as raw material, which are refined and crystallized by electrofusion. They have high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than that of brown corundum. , slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, high temperature thermal stability. It is used to make abrasive tools, suitable for grinding high-carbon copper, high-speed steel, etc. White corundum micropowder is widely used, such as the atomization aesthetic processing of Poly or acrylic art, sandblasting in the production of TV screens, additives for advanced refractories and other ceramics, etc.

Scope of application
Abrasives: Mainly used for: sandblasting, grinding, polishing, cutting discs, grinding wheels, bonded abrasives, coated abrasives, etc.
Refractory materials: precision casting, refractory bricks, castables, etc.
