White Fused Alumina is fused and crystallized in the electric arc furnace under the high temperature of more than 2250°C with high-purity alumina oxide powder. It is characterized by good self-sharpening and high grinding ability. White Fused Alumina can be used in producing vitrified grinding tools, resinoid grinding tools, and it could also be used for abrasives、sandblasting, and refractory application.

For abrasives application, in order to improve the performance, we calcine the grains at 1350°C, and it can be coated by ceramic materials.
