White Fused Alumininium Oxide - China

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
