Cordierite Honeycomb Description

Cordierite Ceramic Honeycomb

Cordierite ceramic honeycomb is made of silicate ceramic (Mg2Al4Si5O18). Cordierite is a commonly used structure ceramic material which has the advantage of energy-efficiency and high-temperature resistance. Cordierite honeycomb 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.

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

Cordierite Honeycomb Characteristics

Cordierite ceramic honeycombs have the following characteristics:

* Cordierite honeycombs can withstand very high temperature.
* Cordierite products 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
