White fused alumina

Process of production

White fused alumina is fused by alumina powder by electric arc furnace under high temperature. It has white color and little higher hardness and lower toughness comparing with brown fused alumina. The micro hard- ness of the product is 2200-2300kg/mm2. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance, good thermal stabil- ity. It’s the high grade refractory materials.

Applications

Dedicated lines produce products for different applications. White fused alumina is high friable and hence used in Vitrified Bonded Abrasives products where cool, fast cutting action is essential and also in the manufacture of high purity Alumina refractories. Other applications include use in Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidised Bed Furnace and Skin / Dental Care.
