The white fused alumina is finished with superior alundum as raw material through electro-melting ,refining and crystallizing. It has many advantages, such as, high pureness, well self sharpness, grinding strength, lower heat output, high efficiency, acid-base and corrosion resistance, high temperature resistance, well heat stability. And the product can be made as grinding too, suitable for grinding high-carbon steel, and high-speed steel, etc., and can also be used as grinding, polishing material,; precision forging; coating material; and special kind ceramic and super refractory, etc..
