As the professional manufacture, we would like to provide you Nextgen Mullite Ceramic Plate. Mullite plate, made of silicate ceramic(3Al2O3•2SiO2), shows advantages of low thermal expansion, good mechanical strength, and resilience at elevated temperatures. Nextgen Advanced Materials supplies Mullite Plates with high quality and fast delivery, and customized products are also available.
The following is the introduction of high quality Nextgen Mullite Ceramic Plate, hoping to help you better understand Mullite Ceramic Plate. Welcome new and old customers to continue to cooperate with us to create a better future! Mullite plate is made of silicate ceramic. The main crystal phase of the mullite plate is 3Al2O3•2SiO2. It has 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.
