White fused alumina is electrically fused in arc furnace with high grade bayer processed alumina as raw material. It is also characterized by its high purity , ability of selfsharpening, better cutting, less heat emit, higher efficiency, acid and alkali resista- nce, good thermal stability. Abrasives tools made of it are suit- able for grinding highspeed,high carbon steel,etc.

     It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for che- mical industry, special ceramics and highgrade refractory mate- rials,ect.
