Product Description


Cordierite ceramic stands out for the following features.Cordierite can be used at high temperatures up to 1200°C thanks to its excellent thermal shock resistance. It also possesses a low thermal expansion coefficient and a low thermal conductivity.Additionally, cordierite has good insulation ability. It comes with a Mohs hardness of about 7, and it is resistant to creeps as well.If you are interested in the mechanical and chemical properties of cordierite, check the table below for more information.


What Is Cordierite Ceramic Used for?


Cordierite ceramic has numerous thermal engineering applications for both households and businesses.

Kiln Furniture

Cordierite is widely used to make kiln furniture for its impressive thermal shock resistance. A cordierite kiln ware is 60% to 70% lighter than a traditional one. You can also get faster heat transfer with such ceramic kiln ware.

Electric Equipment

Cordierite is commonly employed to produce insulation equipment and electric heating elements. For instance, you can find cordierite components used in fuses, thermostats, and lighting technology.

Catalyst Carrier

Cordierite heats up and cools down quickly, and no crack appears because of the temperature change. So, it is a choice material for catalyst carriers, which are mainly used for automobile exhaust purification and industrial exhaust deodorization.
