White fused alumina electrically fused in electric furnace with high grade processed alumina as raw material.
White fused alumina electrically fused in electric furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emits, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, it is widely used for bonded and coated abrasive, polishing, precision casting and so on.
purity alumina by virtue of its chemical stability, high melting point,
high mechanical strength, high hardness, good thermal conductivity,
high insulation and other properties. They're manufactured by the
improved Bayer process.
