Refractory fused zirconia mullite is a highly pure mixture of alumina powder and zirconite fused in a 3 phase electric arc furnace. The mixture is highly homogenized, features low porosity, high thermal conductivity and low thermal expansion coefficient. Available in a large number of grades, upon request.

This material as one kind of high purity refractories, is fused from a mixture of alumina powder and a high purity Zirconite in 3-phase electric arc furnace at a high temperature. It is characterized by its high homogenization and low porosity, high thermal conductivity and low thermal expansion co-efficient at its good slag resistance. It is widely used in refractory and metallurgical industries. It is available in various grades as per requested.
