Cordierite-Mullite Ceramic Honeycomb is made of cordierite and mullite ceramic. Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties. Cordierite also has low thermal conductivity and thermal expansion, while also being cost-effective. Often used as a structural ceramic for kiln furniture applications, it also finds uses in other applications where rapid temperature changes take place. Mullite is an excellent structural material due to its high-temperature stability, strength, and creep resistance. It has a low dielectric constant and high electrical insulation capabilities.

-Catalyst support
Honeycomb ceramics are used as catalyst carriers, mainly used in automobile exhaust purification, boiler exhaust denitrification (NOx), industrial exhaust deodorization, and the removal of toxic and harmful gases.
The carrier of cordierite honeycomb ceramic catalyst used for automobile exhaust purification is mainly cordierite honeycomb ceramic carrier covered with γ -Al2O3.
-Refractory kiln furniture
The mass of extruded honeycomb ceramic kiln ware is 60%-75% lighter than that of traditional kiln ware, and the heat transfer is rapid, which can realize rapid firing. When using it to burn ferrite or other electronic ceramics, it is beneficial to improve the performance of products.
-Wall flow filter
Honeycomb ceramic with porous thin walls can filter and purify carbon particles in diesel gas exhaust.
ACM's Cordierite-Mullite Ceramic Honeycomb is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
