Mullite Light Weight Insulating Refractory Brick
The Description:
Light weight mullite brick is a kind of light refractory material with mullite as the main component. Mullite is a mineral composed of alumina (Al2O3) and silicon dioxide (SiO2), which has good thermal stability and fire resistance.
2.2 Composition of Light Mullite brick Light mullite brick is mainly composed of mullite, alumina, silica and other auxiliary materials (such as foam agent, blowing agent). Among them, the content of mullite is usually between 60% and 80%.

Main characteristics of lightweight mullite brick
1. Low density Lightweight mullite bricks have a low density, usually between 0.5 and 1.2g/cm³. This makes it have a good lightweight effect, helping to reduce structural load and save energy.
2 .Good fire resistance Light mullite brick has excellent fire resistance, can maintain good strength and stability in high temperature environment. It can withstand high temperatures up to 1400°C~1600°C, suitable for a variety of fire-resistant occasions.
3 .Excellent thermal insulation Due to its low density and microporous structure, lightweight mullite bricks have good thermal insulation properties. It can effectively insulate and hold heat, reduce heat loss and improve energy efficiency.
4 .Corrosion resistance Lightweight mullite bricks have good corrosion resistance and can resist the erosion of acids, alkalis and other corrosive media. This makes it widely used in industries such as chemical and metallurgy.
