белый плавленого глинозема / огнеупорного материала

Refractory material, abrasive material, castable refractory, refractory, fused alumina, carborundum, emery grain, tabular alumina, white fused alumina character: White fused alumina has higher hardness and slight lower toughness comparing with brown fused alumina. White aluminum oxide 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 It is a kind of important raw materials used to manufacture abrasives and advanced refractory. white fused alumina application: As the abrasive materials, white aluminum oxide is suitable for grinding high-speed, high carbon steel, as loose grains, white fused alumina widely used for bonded and coated abrasives , polishing, precision casting and so on . white fused alumina melting : White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. .
