Ceramic Honeycomb (Used In Vehicle)

Ceramic Honeycomb (Used In Vehicle)Detail Introduce: The honeycomb ceramic substrate 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 providehigh surface for the precious metal catalysts that convert noxious emission into water vapor, carbon dioxide and so on.
