белый плавленого глинозема

White fused alumina oxide is electrically fused the furnace with high grade bayer processed alumina as raw material. It has higer hardness and slightly lower toughness compared with brown fused alumina. It is also characterzed by its high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency ,acid and alkali resistance,good thermal stalility.Abrasives tools mede of it are suitable for grinding high-speed,high carbon steel,etc. It also can be used as materials for grinding and polishing,precision casting,spraying and coating,medium body for chemical industry,special and high-grade refeactory materials,etc.
