Material: cordierite &mullite
It is used in heat shock applications that would crack and shatter most other ceramic materials, it can survive thousands of heating and cooling cycles.
it is characterized by high purity, high density, high strength and good thermal shock resistance, is mainly used as high temperature (1350-1650oC) kiln linings or kiln furniture in ceramics and refractories industries, gas combustion furnace in petrochemical industry and other high temperature services where thermal shock happens frequently.
