Doc Poc Scr Cordierite Honeycomb Ceramic Catalyst Substrate

The three-way Catalytic Converter mainly consists of ceramic and metal carriers. Both serve to provide support and reaction interface for the catalyst, thereby efficiently purifying exhaust gases. Ceramic carriers are commonly used in the market due to their low cost and high temperature resistance. Metal carriers are typically used in high-performance or luxury vehicles. They have fast heat conduction and high strength. The carrier itself does not purify vehicle exhaust gases; it is mainly the surface coated with precious metals such as palladium, platinum, and rhodium that converts harmful gases in the vehicle into harmless ones.
