Silicon-mullite brick
Characters of Silicon-mullite brick:
Mullite (3Al2O3.2SiO2) and silicon carbide (SiC) are used as the main mineral composition of such burnt brick. It has advantages of resisting high temperature from mullite and wear-resisting corrosion resistance and good heat conduction performance from SiC.
According to the previous user feedback, Silicon-mullite brick is of good thermal shock resistance, good high temperature strength, erosion resistance, not peeling off, don't break, longer service life.
Applications of Silicon-mullite brick:
Silicon-mullite brick is mainly used for small and medium-sized the transition zone of cement kiln, decomposition furnace and cooling machine.
