White aluminium oxide is electrically fused in are furnace with high grade bayer processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina.
It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. Abrasive tools made of it are suitable for grinding high-speed, high carbon steel, etc.
It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.
