* Uniform expansion* Excellent thermal shock stability* High load softening point* Small high temperature creep value* High hardness* Good chemical resistance

Sintered Mullite is choosed the natural high-quality bauxite, through multi-level homogenization, calcined at over 1750℃. It is characterized by high bulk density, stable quality, stable thermal shock resistance, low index of high temperature creep and good chemical corrosion resistance performance

The applications of mullite

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

Mullite rarely occurs as a mineral in nature. In fact, the word mullite is derived from the Isle of Mull off the English coast, where the only naturally occurring deposits of mullite have ever been found.

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.

The preparation of high‐purity mullite powders (3Al2O3· 2SiO2) was examined using aluminum salts or boehmite and fumed silica.

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.
