High purity fused refractory mullite is a fused mixture of alumina powder and high purity silica sand using a 3 phase electric arc furnace. The material comes in a wide range of grades, according to customers requirements.

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.
