White fused Alumina, a kind of high-grade refractories,was made from the high quality alumina by melting above ***0℃ in the electric arc furnace and cooling. It is white white with the main crystal phase alpha-AL2O3.the white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

White fused alumina for abrasives is used in the grinding of heat sensitive alloys.taking advantage of its friability and cool cutting ability,it is widely used in precision grinding of high speed steels,segments and internal grinding wheels.
