Good Thermal Shock Resistance Mullite Brick
Mullite brick is characterized by good high temperature resistance and good thermal shock
resistance, whick comes into being mullite through calcine with clay, high alumina materials and
ceramics.
1. Sulfuric cracking furnace.
2. Fibrous glass furnance.
1. Low permanent linear change on reheating.
2. Good Thermal Shock Stability.
3. High dense structure.
