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 for firing a green honeycomb ceramic body in a kiln may include heating the green honeycomb ceramic body in four stages. The first stage may include heating the green honeycomb ceramic body from room temperature to a first temperature that at a first heating rate that is greater than or equal to about 75° C./hr. The second stage may include heating the green honeycomb ceramic body from the first temperature to a second temperature at a second heating rate that is less than or equal to the first heating rate. The third stage may include heating the green honeycomb ceramic body from the second temperature to a hold temperature at a third heating rate that is less than or equal to the first heating rate. The fourth stage may include holding the green honeycomb ceramic body at the hold temperature to remove residual carbon.
