Heat Storing Body

The automobile uses honeycomb ceramic as carriers. Owing to large specific surface area of the carrier, being able to be coated with the active catalytic components of precious metal enough, honeycomb ceramics are suitable for fabricating emission catalytic converter in diesel or gasoline vehicle to get through emission such as CO,NOX and hydrocarbon etc,,purified.
