Cordierite ceramic rod
Abstract
Cordierite Rod is a commonly used structure ceramic material which has the advantage of energy-efficiency and high-temperature resistance. Supreme Ceramic Materials (SCM) supplies Cordierite Rod with high quality and fast delivery and customized products are also available.
Cordierite Rod Description
Cordierite ceramic rod is made of silicate ceramic cordierite (Mg2Al4Si5O18). Cordierite is a commonly used structure ceramic material which has the advantage of energy-efficiency and high-temperature resistance. It is widely used on barbeque grill, burn oven, convection oven, gas oven, rotary oven, natural gas heater, space heater crucible and various heating equipment, etc.
