Mullite Insulation Brick

Mullite Insulation Brick is a kind of quality refractory insulation materials for resisting high temperature with features of light weight, low thermal conductivity, thermal insulation and high compression strength in the high temperature furnaces or kilns. Mullite Insulation Bricks are mainly used for the top of hot blast stove, stack and bottom of blast furnace, regenerative chamber of glass melting furnace, lining of ceramic high temperature furnace and so on.

Mullite Insulation Brick Introduction:

Thermal insulation mullite brick is a kind of brick made by mixing mullite and thermal insulation material. Primarily used as a form of insulation in high temperature applications such as kilns, furnaces and other high temperature areas, this brick is also resistant to chemical attack.

Mullite insulation brick is made from mullite as main crystal phase, the alumina content is between 40~70%, it is a kind of high alumina refractory. Except mullite, lower alumina content mullite insulation brick also has a small amount of glass phase and cristobalite. The advantage of mullite lightweight insulation brick is that it can be exposed to flames and used directly in high temperature furnace linings. Mullite light weight insulation brick is a refractory insulation material widely used in emerging industrial furnaces and high temperature equipment.

Mullite Insulation Brick Advantages:

1.Low thermal conductivity
2.High strength and wear resistance
3.Low expansion coefficient
4.Low porosity

This series of mullite bricks are made from high purity raw materials by unique techniques, thus largely weakens bad effects of impurities and structure shortage on mullite brick performance. The mullite bricks are also an ideal energy saving product and are widely used for lining and heat insulation layer of industrial furnaces and kilns in metallurgy, machinery, ceramic, chemical industry, and so on. While being used for furnace lining, they are hardly eroded by melting liquid.
