Silica cordierite mullite for insulating white mullite firebrick

 

 

 

Mullite (or mullite, aluminum silicate) refers to a series of minerals composed of aluminosilicate.It’s widely used for refractory materials, ceramics, metallurgy, casting, electronics and other industries have the characteristics of high temperature resistance, high strength, small thermal conductivity, remarkable energy-saving effect and the like, and are suitable for lining of petroleum cracking furnaces, metallurgical hot blast stoves, ceramic roller kilns, tunnel kilns, electric porcelain drawer kilns, glass crucible kilns and various electric furnaces.

 

 

 

Mullite is a high-quality refractory material.Mullite is a mineral produced by aluminosilicate at high temperature. Mullite is formed when aluminosilicate is heated artificially.
