Mullite sand is aluminum silicate refractory materials, normally used in stainless steel precision casting technology.

SEPPE Mullite is a good, low cost refractory ceramic with a nominal composition of 3Al2O3•2SiO2. The raw materials for mullite are easily obtainable and are reasonably priced.

Mullite sand is a rare silicate mineral. Mullite sand is made by kaolin through high heat sintering. Mullite sand origin in mainly distributed in the zhangqiu shandong and north of anhui and so on.

Mullite powder is sintered at a high temperature at about 1000 degree. So mullite has a higher refractory temperature up to 1750 degree. We are comitted to produce mullite, mullite powder roduction of mullite, mullite powder products by the synthesis of high temperature calcination.

Mullite is the mineralogical name given to the only chemically stable intermediate phase in the SiO2 - Al2O3 system. It is a high alumino-silicate produced by calcining low alkali clays in a rotary kiln.Mullite is used in the manufacture of high quality fired and monolithic refractory product.
