White corundum is a kind of high-purity corundum crystal which is made by using aluminum oxide powder as raw material and melting and recrystallizing at high temperature in an electric arc furnace. The color is white, hence the name white corundum. White corundum micro-powder has good chemical stability, slightly higher hardness than brown corundum, slightly lower toughness than brown corundum, can be used as a fixed abrasive and coated abrasive, wet or dry blasting; Hardened steel, high carbon steel, alloy steel, high carbon steel and other materials with strong hardness and strong resistance to warfare; also suitable for grinding and polishing of piezoelectric crystals, semiconductors, monocrystalline silicon and polycrystalline silicon, and can also be used as insulating materials, Special ceramics and advanced refractory materials.
