Abstract
In order to obtain a honeycomb structural body having excellent mechanical strength, which can eliminate a waste use of a catalyst, incomplete cells at an outermost peripheral portion of the honeycomb structural body are sealed selectively by ceramic materials. An incomplete cell does not have a square cross section if the complete cell has a square cross section, and is preferably defined by the cell having an area not more than 90% as that of the complete cell.
Claims7
A ceramic honeycomb structural body comprising an outer peripheral wall, partition walls forming complete cells extending along a central portion of the body and incomplete cells extending along an outer periphery of the body, said incomplete cells being partially defined by said outer peripheral wall, wherein fewer than all of said incomplete cells are sealed by ceramic materials.
