Abstract

PURPOSE: To enhance the efficiency in cleaning exhaust gases by providing a plurality of projections on the inside walls of through-holes for passing exhaust gases in honeycomb structure.
CONSTITUTION: The ceramic honeycomb structure 1 consisting mainly of cordierite and used for cleaning the exhaust gases emitted from an internal-combustion engine of an automobile or the like has a plurality of through-holes 2. The inside walls of the through-holes 2 are provided with a ceramic layer 3 having a plurality of the projections 3a arranged irregularly thereon. To produce the structure, pellets of a combustible organic material such as a resin or carbon are packed into the through-holes 2 of the honeycomb structure 1, and then a slurry of a mixture containing a cordierite powder, methyl cellulose and water is poured into the gaps left after the packing. Further, air in the through-holes 2 is completely evacuated by a vacuum pump or the like, followed by drying and sintering, whereby the organic material is burned away to obtain the structure A provided with the projections 3a.
