White corundum is made of high-quality aluminum oxide powder as raw material, and is crystallized by high-temperature melting. It is white, its hardness is slightly higher than that of brown corundum, and its toughness is slightly lower. It has high purity, good self-sharpness, strong grinding ability, low caloric value, high efficiency, acid and alkali corrosion resistance and high temperature thermal stability. White corundum is a kind of high-grade refractory material.
Our White Fused Alumina is electrically fused in arc furnace under the high temperature of above 2000ºC with high grade processed alumina as raw material. It is divided into a variety of particle sizes after crushing, shaping, magnetic separation and iron removing.
