Product Description

Description

White fused alumina is high grade refractory materials,which made from the high quality alumina by melting above 2000 ℃ in the electric arc furnance and cooling.
Application:
White fused alumina is suitable for manufacturing ceramic or resinous abrasiveproducts, which are used to grind high carbon steel, high speed steel and hardened steel, etc.
1. As abrasive tools and  lapping ,polishing materials, coating materials.
2.Non-skid title ,presure blasting when a high purity and highly frable abrasive is needed.

3. As chemical catalysts, additives of special ceramics and high-grade refractory.
