Silica mullite brick is made of sintered bauxite and high dense SiC silicon carbide by process of pressing and firing at high temperature .
Silica-mullite bricks are characterized by good performance of thermal shock resistance, better wear-resistance and spalling resistance. It’s a good choice for cement kiln and applied in transition zone, cooling zone and outlet.
Classification: GM-1550 1650 1680
High quality silicon mullite brick is the best refractory material for large cement kiln
