LOW EXPANSION CEMENT COMPOSITIONS FOR CERAMIC MONOLITHS

摘要

Disclosed are cement compositions for applying to honeycomb substrates. The cement compositions contain an inorganic powder batch composition; a binder; a liquid vehicle; and an elastic modulus reducing additive. The elastic modulus reducing additive can contain a ceramic fiber or a monohydrated alumina. The cement compositions are well suited for forming ceramic diesel particulate wall flow filters. Also disclosed herein are end plugged wall flow filters that include the disclosed cement compositions and methods for the manufacture thereof.
