Keramiksubstrat

Honeycomb ceramic is used as a carrier in a three way catalytic converter for automobile industry with its special large surface area. The product can load enough noble metal and other catalytic reactive components, making the Carbon Monoxide (CO), Hydrocarbons (HC), Nitrogen Oxides (NOX) in car exhaust emitted after purifying. Meanwhile, the wall-flowing type of filter with porosity and thin wall is able to filter particulates in the diesel exhaust gas (about 500°C).
