Fused white alumina is a kind of high-grade and middle level refractory material, with the host lattice of α –Al2O3 and in white and crystal-like color. The products are of high bulk density and low air hole rate, which can efficiently improve dimensional stability and thermal shock resistance of materials.
Fused white alumina is widely used in steel, cement, ceramics,abrasive, petrochemical, and other industries.
