产品描述

Fused Mullite is manufactured by fusing a mixture of high purity Alumina and pure quartz in a tilting type arc furnace at a temperature around 2000 degrees centigrade.
Controlled cooling of the molten mass ensures a high degree of mullitization characterized by well defined columnar crystals.Fused Mullite is one of the main raw materials used by the refractory industry for applications requiring thermal shock resistance and corrosion resistance.
