Brief Introduction
The silica mullite brick produced by our company are made of special high-alumina bauxite clinker and high-quality silicon carbide as the main raw materials, through high-pressure molding and high-temperature sintering. The product has high compressive strength at room temperature and high-temperature structural strength, and good thermal shock stability. During use, a protective layer is continuously formed, with good wear resistance and strong anti-stripping properties.
