White fused alumina is fused by alumina powder by an electric arc furnace under high temperature. It has a white color and a little higher hardness and lower toughness comparing with brown fused alumina. The microhardness of the product is 2200-2300kg/mm2. White fused alumina has higher hardness and slightly lower toughness comparing with brown fused alumina. White fused alumina is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s high-grade refractory materials.
Dedicated lines produce products for different applications. White fused alumina is highly friable and hence used in Vitrified Bonded Abrasives products where cool. The fast cutting action is essential and in the manufacture of high purity Alumina refractories. Other applications include Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces, and Skin / Dental Care.
