Mullite Plate Description

Mullite plate is made of silicate ceramic. The main crystal phase of the mullite plate is 3Al2O3·2SiO2. It has a low thermal expansion, good mechanical strength, and resilience at elevated temperatures. Raw mullite materials are easily obtained and 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.

Advanced Ceramic Materials (ACM) is a trusted supplier of mullite ceramic plates.
