Light weight mullite insulating brick is made from pure mullite and adding alumina powder according to different type sintering in high temperature.
►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
