Product Details

Product description:

This White Fused Alumina  is based on Bayer alumina, to be electrically fused at high temperatures. It has higher hardness and lower toughness than brown fused alumina. Its grinding tools are suitable for the grinding of high carbon steel, high speed steel and chilled steel. It can also be used as a polishing medium and precision foundry sand, spray and coating materials, catalyst supports, specialty ceramics and advanced refractories. White Fused Alumina is a high quality raw material made from melt refined crystals. It has high purity, self-sharpness, good acid and alkali resistance, thermal properties and stability. It has a slightly higher hardness than corundum. It has a slightly lower toughness but a higher purity. It is produced by controlling the melting of alumina in an electric arc furnace. White fused alumina is iron free, ultra pure and extremely hard.
