Mullite Ceramic (3Al2O32SiO2)

Mullite (3Al2O32SiO2) is an alumino silicate ceramic combining low thermal expansion, good mechanical strength, and good high-temperature stability. Mullite ceramic is used extensively in the steel and glass industries. It is also used as a lower cost alternative to alumina, with slightly better thermal shock properties.

The advantages of mullite ceramic:

– Good thermal shock properties

– Low thermal conductivity

– Good wear resistance and resistance to creep

The application of mullite ceramic:

Typical applications include kiln furniture, furnace center tube, heat exchange parts, heat insulation parts, rollers and other customized parts.
