White corundum is a kind of fused alumina products made from high quality alumina powder. White corundum is characterized of high hardness, high purity, excellent self-sharpening, big grinding power, less heat, high efficiency, acid corrosion, high temperature resistance, good thermal stability. As a refractory material, white corundum can be pickling white corundum powder or aggregate granules.

Fused White Corundum:
Fused white corundum is mainly processed by high temperature smelting. The main components of white corundum is Al2O3 with content not less than 98.5%, less impurities, high purity, white in color. Since the excellent hardness, bulk density and relatively high specific gravity, fused white corundum is widely used as high temperature refractory materials, abrasive, polishing, sandblasting and other electronic industries.
