Ceramic Honeycomb Substrate

Ceramic honeycomb catalysts have been widely used since the 1980s. They can be extruded in a variety of shapes and cell densities. Ceramics are often used where the required catalyst volume is more than is practical for wire mesh catalysts.

Ceramics make for very dimensionally stable catalyst supports over the range of operating temperatures. Ceramic substrates can carry a heavier amount of coating than metallic supports, which gives ceramics the advantage in applications where catalyst deactivators are present or where very high levels of precious metals are needed to reach the desired performance.
