Insulating Mullite 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℃.

1.High porosity.

2.Low volume density.

3.Good insulation effect.

4.High mechanical intensity.

5.Low thermal conductivity.

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.
