Description Of Mullite Insulation Bricks:

The light weight mullite insulation brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life.    For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

Performance Mullite Insulating Firebrick:

The refractoriness is high, can reach to more than 1790 degrees centigrade.    The RUL is 1600~1700 degrees C. The compressive strength at normal temperature is 70 ~ 260MPa.    The thermal shock resistance is good.    There are two kinds of mullite bricks: sinterted mullite and fused mullite brick.

Characteristics of Mullite Insulating Firebrick:

The main material of sintered mullite brick is high alumina bauxite as the main raw material, adding a small amount of clay or raw bauxite as binder, it is made by molding and sintering.    Fused mullite brick with high bauxite, commercial alumina and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, after molding, can adopt the reduction electrofusion method to manufacture.    The crystallization of the electric cast mullite is larger than that of the sintered mullite, and the thermal shock resistance is better than that of the sintered product.    Their high temperature performance mainly depends on the content of alumina  oxide and the uniformity of the distribution of mullite and glass.
