Abstract: Methods of firing ceramic-forming honeycomb bodies are disclosed that include heating the honeycomb bodies and blocking furnace gases from flowing through the honeycomb body by placing a layer selected from the group consisting of a graphite layer, a graphite-containing layer, an activated carbon layer, or an amorphous carbon layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the honeycomb body. The layer oxidizes to form a porous layer after firing to a first temperature, and furnace gases flow through the honeycomb body.

Abstract: Disclosed is a honeycomb catalyst support structure comprising a honeycomb body and an outer layer or skin formed of a cement comprising an amorphous glass powder with a multimodal particle size distribution applied to an exterior surface of the honeycomb body. The multimodal particle size distribution is achieved through the use of a first glass powder having a first median particle size and at least a second glass powder having a second median particle size. In some embodiments, the first and second glass powders are the same amorphous glass consisting of fused silica. The cement may further include a fine-grained, sub-micron sized silica in the form of colloidal silica. The cement exhibits a coefficient of thermal expansion less than 15×10−7/° C., and preferably about 5×10−7/° C. after drying.

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