Corundum mullite brick using synthetic mullite as raw materials, is a kind of refractory products with mullite as main crystal phase. Corundum mullite by sintering and electric melting method. Corundum mullite synthesis method is: the production of first used without impurities, pure raw materials, ingredients according to the theory of mullite composition, then the material after fine grinding, pressed into the material block, and calcining at high temperatures.

Sintering production of corundum mullite, the main ingredients are: natural bauxite and kaolin; alumina and silica; kaolin clay or wax stone; corundum and silica.
Henan Sailong Technology Company is a collection of scientific research, production as one of the high-grade refractory products production base, has a sales network covering the whole country. The factory for customers throughout the country provide considerate service.
