White aluminum oxide is electrically fused in the furnace with high grade bayer processed alumina as raw material. It has high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel , excite also can be used as materials for grinding and polishing, precision casting, spaying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.
