Silica Mullite Brick is a new type of refractory brick composed of two parts: working layer and heat insulation layer. The working layer is made of high-quality special grade bauxite and silicon carbide as the main raw materials. The heat insulation layer is made of low thermal conductivity hot aluminum silicate material, which is obtained by high pressure molding and special firing process, , and the bonding surface between the two parts is interlaced to form composite brick.
