Abstract: A method of plugging channels of a honeycomb body and a honeycomb body including plugged channels. The method includes applying a shear force to a plugging mixture including a plurality of inorganic particles, clay, and a liquid vehicle to alter the viscosity of the plugging mixture from a first viscosity prior to the vibrating to a second viscosity which is less than the first viscosity. A honeycomb body is placed into contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels. Application of the shear force is stopped or reduced to increase the viscosity of the portion of the plugging mixture in the plurality of channels to greater than the first viscosity.

The pass-through catalytic substrate can include a plurality of porous ceramic beveled corner portions positioned at intersecting corners of the substrate walls within the flow channels. In one example, the porous ceramic beveled corner portions each include a heat capacity less than about 1.38 J/cm3/K. In another example, a catalytic washcoat layer can be provided for coating the porous ceramic substrate walls and the porous ceramic beveled corner portions. Methods for producing a pass-through catalytic substrate also provide porous ceramic beveled corner portions.

Abstract: A method of plugging a permeable porous cellular body (14) comprises: contacting the permeable porous cellular body (14) with a plugging mixture (100), the permeable porous cellular body (14) defining a plurality of channels (26); forcing the plugging mixture (100) into the plurality of channels (26) until a maximum, self-limiting, depth (114) of plugging mixture (100) is disposed within the plurality of channels (26); and maintaining a constant flow rate of the plugging mixture (100) into the plurality of channels until (26) a pressure on the plugging mixture (100) elevates to a predetermined pressure. Alternatively, the method comprises forcing the plugging mixture (100) into the plurality of channels (26) utilizing the application of a constant pressure over time until a maximum, self-limiting, depth (114) of the plugging mixture (100) is disposed within the plurality of channels (26); and maintaining the constant pressure applied to the plugging mixture (100) until flow of the plugging mixture (100) into the channels (26) decays from an initial flow rate to a predetermined flow rate.
