Ceramic Honeycomb Substrate Description:
Ceramic Honeycomb 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. Ceramic Honeycomb as catalytic converter substrate low thermal expansion coefficient, good thernal shock resistance. Ceramic Honeycomb Substrate ate made of cordierite enjoys the merits of very low thermal expansion coefficient, high specific surface area, low pressure drop, rapid light-off and unique structures which are perfect for car catalytic converter. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals. The shape will be round, oval or racetrack with 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi cells that provide high surface for the precious metal catalysts that convert noxious emission into water vapor, carbon dioxide and so on.
