Title:
Honeycomb structure containing a cement outer cover and cement for it
Document Type and Number:
Japanese Patent JP6082065
Kind Code:
B2
Abstract:
A honeycomb catalyst support structure including a honeycomb body and an outer layer or skin formed of a cement is described. The cement includes 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.
