Silica-Mullite Bricks Description

Silica-Mullite Brick is a fired brick composed of mullite (3Al2O3.2SiO2) and silicon carbide (SiC) as main minerals. It is characterized by the high temperature resistance of mullite and the wear resistance, corrosion resistance and thermal conductivity of silicon carbide.

The feedback from the user, reflects that, the silica-mullite brick has good thermal shock resistance, good high temperature strength, anti-erosion during use, no peeling, no breakage, and prolonged service life. Silica-mullite bricks are mainly used in the transition zone, decomposition furnace and cooling machine of small and medium-sized cement kiln.

Silica-Mullite Bricks Manufacturer

Rongsheng refractory bricks manufacturer, the production of rotary kiln brick lining silica-mullite bricks are a special high-alumina bauxite clinker and silicon carbide as the main raw material, through the special sintering process made of Al2O3-SiO2-SiC refractory. Its load-softening temperature, thermal shock resistance, wear resistance and corrosion resistance are superior to high-alumina bricks, even better than spinel bricks. This is because the silica-mullite brick can continuously form a protective layer during use and can reduce the loop.
