Mullite heater plate is made of silicate ceramic mullite (3Al2O32SiO2). Mullite 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 China Special Ceramic Parts. Its workability allows an extensive range and flexibility in fabrication.
China Special Ceramic Parts, Inc. (CSCPI) is a trusted supplier of mullite ceramic products.
