Honeycomb Ceramic (Used In Vehicle)detail
Introduce:
The honeycomb ceramic substrate is made of cordierite, and it is used for car catalytic converter. The cells density can be 100 cpsi, 300 cpsi ,400 cpsi or 600 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.
Specification of catalyst carrier (straight hole) used in gasonline engine car.
