Fused Mullite is manufactured by fusing a mixture of high purity Bayer Alumina and pure Quartz in a tilting type arc furnace at a temperature around 2000 deg C.  Controlled cooling of the molten mass ensures a high degree of mullitization characterized by well defined columnar crystals.The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into desired size fractions
