Al2O3 99.5% Gong Yi HY White Fused Alumina

White fused alumina is made from high quality Bayer-processed alumina by fusing in an electric arc furnace at high temperature. It has high hardness and better cutting
characteristics. It is suitable for manufacturing of vitrified
and resinoid tools, and for lapping, polishing and blasting.

It can be also used to make engineering ceramic and superior
refractory products.
