Dense fused corundum is a high-grade refractory material, the main crystal phase is α-AL2O3, and the color is gray. The product has the characteristics of high melting point, high bulk density and low porosity. It has excellent wear resistance, slag resistance, volume stability and thermal shock resistance at high temperature. It is considered to be the best refractory raw material in the corundum series.
