1. Main Characters: The raw material for mullite insulation brick is mullite. This kind of brick has high structure strength, low creep, small thermal expansion rate, strong resistance to chemical erosion and good thermal shock resistance.
2. Applications: Can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much.
