1. White fused alumina description: White fused alumina/white corundum is made from high quality alumina by being melted above 2000 centigrade in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. 2.
