Silica-mullite red brick JXGM-H
Silica-mullite bricks are made mainly from high-quality bauxite and high-quality silicon carbide. Our proprietary production process controls the oxidation of the silicon carbide so that a dense glaze film forms on the brick surface at high temperature, which secures the excellent performance of this series and gives users satisfactory service results. The JX silica-mullite multifunctional hanging brick is used in the kiln hood of cement kilns, with a service period of up to 24–30 months.
