Ceramic Honeycomb Substrate Introduction
We manufacture honeycomb ceramic products in 6 series and 200 specifications and varieties, and they approach international advanced level, such as the Korea market. They well match active components of catalysts, have thin pore wall, large geometric specific area, low thermal expansion coefficient and good thermal impact resistance, while widely used in various fields. The products are the ideal carrier for catalysts and heat exchanger of purifying waste gas in environmental protection and chemical industry, and also the ideal high-temperature filtering materials of the metallurgy and casting industry.

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.
The material for catalyst ceramics is cordierite, The major features for such cordierite are low thermal expansion coefficient, good thermal shock resistance, high anti-acid, anti-alkali and antii-erosion function and good mechanical strength, high specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400 CPSI. The usual CPSI for catalytic converter substrate is 400. The usual cells density for honeycomb ceramic substrate is 400 CPSI. The shape of honeycomb ceramic is round, racetrack, ellipse and other special shape according to the customer's requirement in order to meet the different cars models requirements. We offer honeycomb ceramic substrate with different specification and different cars for the car converter as the customer request.
