Product Description

The following is the introduction of high quality Nextgen Mullite Ceramic Tube, hoping to help you better understand Mullite Ceramic Tube. Welcome new and old customers to continue to cooperate with us to create a better future! Mullite tube is made of silicate ceramic mullite. The main crystal phase of mullite tube 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. It is well suited for the casting of special shapes and larger tubes.
