Cordierite Plate Description

Cordierite Ceramic Plate

Cordierite ceramic plate is 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 plate is widely used on a barbeque grill, burn oven, convection oven, gas oven, rotary oven, natural gas heater, space heater crucible, and various heating equipment, etc.

China Special Ceramic Parts, Inc. (CSCPI) is a trustworthy supplier of cordierite ceramic products.

Cordierite Ceramic Plate Characteristics

Cordierite plate has the following characteristics:

* Cordierite ceramic plate can withstand very high temperatures.
* Cordierite plates have a low thermal expansion, which is necessary when firing products quickly through a kiln.
* Excellent thermal shock properties
* Good mechanical strength
* Can be used up to approximately 1200°C
* Outstanding crack-resistance
