Mullite Ceramic Parts

Mullite ceramic part is made of silicate ceramic mullite. The main crystal phase of mullite ceramic part is 3Al2O3·2SiO2. It has low thermal expansion, good mechanical strength, and resilience at elevated temperatures

Mullite materials are easily obtained and are reasonably priced. It is certainly one of the most important oxide materials for both conventional and advanced ceramics. Its work ability allows an extensive range and flexibility in fabrication.

The mullite ceramic part is sintered under high temperature with high- purity raw materials and advanced production technologies.

Product Features:

1)low thermal expansion
2)large specific heat capacity
3)high specific surface area
4)low pressure drop
5)small thermal resistance
6)good thermal conductivity
7)good heat-shock resisting ability
