Mullite Insulating Brick - Lightweight High Purity Alumina 50-85% | Low Thermal Conductivity, High Refractoriness, Energy Efficient, Flame Contact Capability, Long Service Life

We are engaged in offering excellent quality Mullite Insulating Brick to our valuable clients. Lightweight mullite heat insulating refractory brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. The Al2O3 content is 50-85%.

Features:-
1.Low levels of iron and other impurities
2.High mechanical intensity
3.High refractoriness, can contact with the flame directly, suitable for various atmosphere
4.High porosity, low volume density, low thermal conductivity
5.Good heat insulating performance and energy-efficient
6.Low creep rare at high temperature,good thermal shock stability
7.Chemical corrosion resistance
8.Long service life

Application:-
Lightweight heat mullite insulating refractory brick can be in direct contact with the flame,this insulating brick can be used as linings or as thermal preservation layers in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry, machinery industry, such as blast furnace, hot blast stoves ,electric arc furnace, cement kiln,melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other thermal industrial equipment.
