It is white, hard and brittle than brown corundum, and has strong cutting force. Good chemical stability. It has good insulation. The microhardness is 2200 - 2300kg / M. It can be used for consolidation abrasives and coated abrasives, wet or dry jet sand, super fine grinding and making refractory materials. It is suitable for processing hardened steel, alloy steel, high speed steel, high carbon steel and other materials with high hardness and high tensile strength. It also adapts to the grinding and polishing of piezoelectric crystals, semiconductors, monocrystalline silicon and polysilicon, and can also be used as touch media, insulators, special ceramics and refractory materials.
