Honeycomb Ceramic Substrate Used In Vehicle
Honeycomb ceramic substrate is made of cordierite, and is used for car catalytic converter. The cells density can be 100 cpsi, 300 cpsi or 400 cpsi. The shape will be round, oval or racetrack. We can supply both ceramic element coated with noble metals of PT, Pd, Rh and ceramic element without noble metals.
The corundum/mullite and cordierite/mullite complex thermal storage honeycomb ceramic developed by our company has the following notable characters: perfect high temperature resistance, anticorrosion, perfect thermal shock stability, high mechanical strength, large thermal storage capacity, advantaging heat conduction property, energy conserving result and service life are improved greatly.
