Silicon Mullite Brick
Its main raw materials are high grade bauxite and silicon carbide, which are formed by high-pressure molding and high-temperature calcination by adding appropriate amount of additive agents. The brick has some good high temperature performance like anti-erosion and anti-scouring. It is ideal kiln liner material for cooling, transition zone of new dry method rotary cement kiln.
