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.
Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.
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.
Benefits of Products:
1)Low thermal expansion coefficient
2)High porosity of hole on the wall, good liquidity and uniform distribution.
3)High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong.
4)The pressure drop is small.
5)Cold start performance is good, low light-off temperature, high conversion efficiency.
