Mullite Insulation Brick

Mullite insulation brick holds special grade mullite (3Al2O3•2SiO2) as the major crystal phase. The content of alumina in mullite insulating brick is 42%-72%. The service temperature could be 1250℃-1600℃.

Performance Characters:

1.High porosity.
2.Low volume density.
3.Good insulation effect.
4.High mechanical intensity.
5.Low thermal conductivity.

Application:

Mullite insulating brick is widely used in different types of high temperature furnaces or kilns. For example, it is widely used for hot-blast furnace, regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace lining of petroleum cracking system, shuttle kiln, roller kiln and petrochemical burning pits and so on.
