Thiskind of white fused alumina electrically fused in arc furnace with high gradeprocessed alumina as raw material. It has higher hardness and slight lowertoughness comparing with brown fused alumina. It is also characterized by itshigh purity, ability of self-sharpening, better cutting, less heat emit, higherefficiency, acid and alkali resistance, good thermal stability. As the abrasivematerials, it is suitable for grinding high-speed, high carbon steel, as loosegrains, it widely used for bonded and coated abrasives , polishing, precisioncasting and so on.
