Honeycomb ceramicsubstrates are honeycomb-like structures with thousands of parallelchannels. The walls of these channels provide the surface forprecious-metal catalysts that convert noxious emissions into carbondioxide, nitrogen and water vapor.
Honeycomb ceramicsubstrates enable highly efficient emissions control systems byoffering:
High surfacearea
Low pressuredrop
Rapidlight-off
Thermal-mechanicaldurability
System costefficiency
High transformingefficiency
