Abstract
Ceramic honeycombed structures comprise open-ended cells formed by discontinuities in the cell walls, which discontinuities extend longitudinally through the structure and transversely through the cell walls. The axial discontinuities which enhance the thermal shock resistance of the structures may be formed during extrusion by obstructing the flow of extrudable material through an extrusion die at predetermined locations.
Claims24
A monolithic honeycombed structure of sintered material comprising a plurality of interconnected walls forming open-ended cells extending longitudinally through the structure, said walls including a plurality of discontinuities extending longitudinally through the entire length of the structure and transversely through said walls, said discontinuities having a width substantially less than the distance between junctions of said interconnected walls.
