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 suitabl
e for grinding high-speed, high carbon steel, as loose grains,
it widely used for bonded and coated abrasives , polishing,
precision casting and so on.
