High Grade Mullite Powder

We are instrumental in manufacturing and exporting a world class range of High Grade Mullite Powder in Shizuishan, Ningxia Hui, China.

The mullite powder sold by Shizuishan Jinlin Corundum Refractories Co., Ltd. is a high-quality refractory raw material. It has uniform expansion, excellent thermal shock resistance, high load softening point, high temperature creep value, high hardness, and chemical resistance. Corrosion and other characteristics. Mainly high-purity fused mullite, ordinary fused mullite, all-natural bauxite concentrate mullite and light burning mullite. The only stable binary compound at normal pressure in the mullite AI203-SI02 element system.

Product Performance: Mullite is a mineral produced by alumino silicates at high temperatures. The natural mullite crystals are slender needles and are in a radial cluster. As a thermal barrier coating, quarry is widely used in C/C composites. The only stable binary solid solution in the mullite AI203-SI02 element system at atmospheric pressure is usually synthesized by sintering or electric capacity method. Chemical formula AlxSi2-xO5.5-0.5x density; Mohs hardness of 3.16g/cm3; 6-7 refractoriness: stable at 1800A C, decomposed into corundum and liquid phase at 1810C.

Product Usage:
Refractory materials, ceramics, metallurgy, foundry, electronics and other industries, with high temperature resistance, high strength, low thermal conductivity, significant energy saving effect.
