              White Fused Corundum

      White fused alumina is made from excellent industrial alunima and melted in arc furnaces at high temperature. It has the following characteristics such as nice white colour, firm bulk density, high hardness, good heat-resistance and acid resistance etc. It is not only the excellent raw material for manufacturing abrasive, but also the raw material for grinding and polishing. The product has been widely used in many high-tech industrials such as precision casting, steel refractory, chemical refractory, ceramics, military and electronics.
