| advanced ceramic substrates Corning invented the honeycomb advanced ceramic substrate used at the heart of today?s catalytic converter more than 25 years ago. Our substrates are composed of cordierite, an advanced ceramic that meets the demanding performance requirements of both gasoline and diesel converter applications.
Automotive substrates The substrate is a critical element of an automotive catalytic converter system, significantly influencing engine performance as well as converter efficiency, durability and cost. Our ceramic substrates help meet today?s emission requirements by providing a large surface area in a lightweight, durable package. Each Corning substrate offers the following benefits:
New thin wall and ultra-thin wall substrates offer additional benefits Building on this tradition, we have developed a new generation of thin-wall and ultra-thin-wall substrates that feature an extremely high geometric surface area for even greater conversion efficiency. Our thin-wall 600/4 substrate features 600 cells per square inch and 4 mil walls, while our ultra-thin-wall substrates include a 600/3 and 900/2 version. These substrates can achieve a variety of system benefits, including:
North American, Asian and European manufacturers are selecting Corning ultra-thin-wall substrates for various applications. Together with our standard high-performance substrates, our thin-wall and ultra-thin wall substrate choices give automotive system engineers a variety of cost-effective design alternatives. Diesel flow-through substrates Corning?s large-flow substrates are used in catalytic converters to clean gaseous and particulate emissions from diesel engines, reducing the amount of soot released into the atmosphere. Many light-and medium-duty trucks, urban buses, and highway vehicles are able to meet tightening federal and local emission standards by using a catalyzed Corning substrate. Our substrates deliver consistent, reliable and durable performance under the demanding conditions of everyday diesel operation, including high-pressure pulsations and severe engine and exhaust-system vibration. Their inherently porous nature simplifies the application of wash coats and catalysts. Corning?s diesel emission substrates are available in a variety of cell densities, sizes and contours to suit specific application requirements. Design expertise
Corning has ongoing programs with major automobile, truck and diesel engine manufacturers to help optimize the performance and reduce the cost of the emission-control systems. Our broad technical knowledge and solid understanding of converter systems can support the emission system design effort through the following services:
