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.Small volume density.
3.Good insulation effect.
4.High mechanical intensity.
5.Small 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.

Insulating refractory brick (IRB) is the term used for heat insulating bricks and  covers those heat insulating materials which are applied up to 1000 deg C. IRBs are often mistakenly referred to as rear insulation materials. These bricks are assigned to the group of lightweight refractory bricks and are manufactured on the basis of naturally occurring lightweight raw materials.

IRB is a class of brick, which consists of highly porous fireclay or kaolin. IRBs are lightweight, low in thermal conductivity, and yet sufficiently resistant to temperature to be used successfully on the hot side of the furnace wall, thus permitting thin walls of low thermal conductivity and low heat content. The low heat content is particularly important in saving fuel and time on heating up, allows rapid changes in temperature to be made, and permits rapid cooling. IRB is characterized by the presence of large amount of porosity in it. The pores are mostly closed pores. The presence of porosity decreases the thermal conductivity of the insulating bricks.
