Alumina Ceramic Protection Tubes is widely used In Thermal Processes.
Technical ceramics are favoured in a wide range of electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Ceramics have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard, and have excellent dimensional stability.
