Mullite Heating Protection Tube Description

Mullite Ceramic Heating Protection Tube

Mullite heating protection tube is made of silicate ceramic mullite (3Al2O32SiO2). Mullite is a refractory oxide material combining low thermal expansion, good mechanical strength, and resilience at elevated high 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.

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