YANNUO WHITE FUSED ALUMINA
White Fused Alumina for Abrasives |
White Fused Alumina for Refractory |
Introduction:
White fused alumina belongs to electro-corundum. It is also be called white aluminum oxide, white corundum or white fused aluminum oxide. White fused alumina is obtained from the fusion of high purity calcined alumina in electric arc furnaces. Compared with brown fused alumina, white fused alumina is characterized with high alumina purity, high hardness, chemical stability, high melting point, and large crystal size. It is widely used in coated and bonded abrasives, polishing, precision casting, sandblasting and refractory raw materials.
