Cordierite Ceramic Honeycomb Description

Cordierite honeycombCordierite ceramic honeycomb is made of silicate ceramic cordierite (Mg2Al4Si5O18). Cordierite is a commonly used structure ceramic material which has the advantage of energy-efficient 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.

Cordierite Ceramic Honeycomb Advantages

Cordierite ceramic honeycombs have the following advantages:

* Cordierite / Mullite are minerals formed at high temperature by the reaction of alumina-silica and magnesia. Thus cordierite honeycombs can withstand very high temperature.
* Cordierite products have a low thermal expansion, which is necessary when firing products quickly through a kiln.
* Variety of materials& specifications
* Big specific surface area
* Small resistance loss
* High water absorb rate
* Outstanding crack-resistance
