[Hot Item] Honeycomb Ceramic Catalyst Ceramic Honeycomb Substrate for Car

Ceramic honeycomb substrate is used as catalytic converters of gasoline engines, the honeycomb ceramic catalyst substrates are coated by catalyst. Meanwhile our factory improves the specific surface areas and cuts down the heat capacity to increase the catalytic function. When the noxious emissions pass through, HC, CO and NOX will be converted into harmless components. It's three-dimensional connected mesh structure and high porosity has many advantages, for example, large surface area of slags collection, large inner surface area of filtering, small flow resistance, good filtering effect, etc.






Ceramic Honeycomb is made of cordierite, the cells density can be 100cpsi, 300cpsi, 400cpsi or 600cpsi. The usual cpsi (Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic converter substrate is round, racetrack, ellipse and other special shape as per customers' request. 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.
