Catalytic Converters Core: Metallic vs Ceramic
Ceramics have primarily been used as the substrate for catalytic converters and share a bigger market than metallic substrates. However, metallic substrates have been used since they provide a lower resistance to air flow and require less heat to warm up.
Having a lower resistance to air flow is achievable because the corrugated metal roll allows gases to flow through almost 90% of the total front area while still providing more surface area than the ceramic monolith.
One advantage of metallic substrate is it has a lower specific heat capacity and higher thermal conductivity which allow the converter heated up quickly. It can be moved closer to the engine where exhaust gases are hotter and the converter can react quicker at higher temperatures. This is not applicable to the ceramic substrate because it cannot endure quick heating and might crack.
Another advantage of a metallic substrate is the ability to more easily manufacture the channels in different shapes to increase turbulence of the flowing gas. Increasing the turbulence makes the exhaust come in contact with more catalyst surface area thus converting more of the exhaust into less harmful emissions with a smaller volume.
