Product Description                                                                                                    

Mullite brick is a high alumina refractory with mullite as the main crystalline phase.Generally, the content of alumina is between 65% and 75%.In addition to mullite, the mineral composition of lower alumina contains a small amount of glass phase and cristobalite.The higher alumina content also contains a small amount of corundum.

Mullite brick mainly used for hot air furnace top, blast furnace body and bottom, regenerator of glass melting furnace, ceramic sintering furnace, dead Angle lining of petroleum cracking system, etc.
