Product Description

Fused Mullite

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.

Fused Mullite is one of the main raw materials used by the refractory industry for applications requiring thermal shock resistance and corrosion resistance.
