Gasoline Ceramic Substrate


1.Function
Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic substrate body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a variety of unobstructed parallel channels sized to through 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.he ceramic substrate is made of cordierite, The cells density can be 100 cpsi, 300 cpsi ,400 cpsi or 600 cpsi. The usual cpsi(Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic substrate is round, racetrack, ellipse and other special shape according to the customer’s requirement.
