Mullite Ceramic Heater Plate Description

Mullite Ceramic Heater Plate

Mullite (3Al2O32SiO2) is a refractory oxide material combining low thermal expansion, good mechanical strength, and resilience at elevated temperatures. Raw 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 workability allows an extensive range and flexibility in fabrication.
