What is a Ceramic Substrate?

These substrates can withstand high temperatures >1100°C (2000°F) and are extremely thermal shock resistant (so that they survive rapid heat-ups on frigid mornings). These substrates are very adaptable and can accept a wide variety of catalyst formulations to eliminate pollution from gasoline, diesel, natural gas, hydrogen and other fuels.

The completed substrate is coated with a combination of the appropriate catalytic materials that turn it into a mini chemistry lab and allows large volumes of exhaust to be efficiently treated. At high temperatures of an operational engine, exhaust gases like nitrogen oxides and carbon monoxide meet the catalyst and are converted into harmless nitrogen and water and less harmful carbon dioxide.
