This
kind of white fused alumina electrically fused in arc furnace with high grade
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. As the abrasive
materials, it is suitable for grinding high-speed, high carbon steel, as loose
grains, it widely used for bonded and coated abrasives , polishing, precision
