Silicon mullite brick

• Silicon mullite bricks use high- grade bauxite and silicon carbide as the main raw material, through high-pressure molding, high temperature sintering. Products have cold compressive strength and high temperature structural strength, good thermal shock stability, good wear resistance, high anti-stripping performance, continuously form protective layers in the course of using, and are suitable for the transition zone, cooling zone, the kiln eye and other parts of cement kilns.
