Cordierite Heating Parts Description

Cordierite ceramic heating parts are made of silicate ceramic cordierite (Mg2Al4Si5O18). Cordierite is a commonly used structure ceramic material that has the advantage of energy efficiency and high-temperature resistance. Cordierite heating parts are widely used on barbeque grills, burn ovens, convection ovens, gas ovens, rotary ovens, natural gas heaters, space heater crucibles, and various heating equipment, etc.

Advanced Ceramic Materials (ACM) is a trustworthy supplier of cordierite ceramic products.

Cordierite Heating Parts Characteristics

Cordierite ceramic heating parts have the following characteristics:

* Excellent thermal shock properties
* Low thermal conductivity and thermal expansion
* Good mechanical strength
* Can be used up to approximately 1200°C
* Outstanding crack-resistance
