Product Description

Ai2o3 99% White Corundum/ White Fused Alumina for Abrasive and Refractory

1. Description

White Fused Alumina is produced by fusing alumina block in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has large crystals of Alpha Alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications.

2. Specification

3. Applications

White fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory materials.
