price: contact company for price

Products Description

White fused alumina, with Al2O3 more than 98%, is one of the most popular alumina abrasives. White fused alumina is made from excellent Bayer-processed industrial alumina by fusing in an electric arc furnace at high temperature of 2050degree centigradeunder carefully controlled conditions. It is white in color, a dense mineral and has predominantly large crystals of Alpha Alumina. As a kind of alumina grinding media, it is widely used in polishing, lapping and blasting.

Application:

1. White fused alumina powder is used for making abrasive tools

2. White fused alumina grit also could be used as refractory materials

3. White fused alumina could be used as grinding, lapping, polishing and blasting media
