Feature

 Description:
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.

 

 The main applications are:

1,Sulfuric cracking furnace
2,Fibrous glass furnance.

 

 Specifications:

1,Low permanent linear change on reheating
2,Good Thermal Shock Stability
3,High dense structure

 

 Advantages:

1,High quality;
2,chemical corrosion- resistance
