Cement containing multi-modal fibers for making thermal shock resistant ceramic honeycomb structures
Patent number: 8480781Abstract: A ceramic honeycomb structure comprised of at least two separate smaller ceramic honeycombs that have been adhered together by a cement comprised of inorganic fibers and a binding phase wherein the smaller honey-combs and fibers are bonded together by the binding phase which is comprised of an silicate, aluminate or alumino-silicate. The fibers have a multi-modal size distribution in which some fibers have lengths of up to 1000 micons and other fibers have lengths in excess of 1 mm. The cement composition may be made in the absence of other inorganic and organic additives while achieving a shear thinning cement, for example, by mixing oppositely charged inorganic binders in water together so as to make a useful cement composition for applying to the smaller honeycombs to be cemented.Type: GrantFiled: June 24, 2010Date of Patent: July 9, 2013Assignee: Dow Global Technologies LLCInventors: Jun Cai, Aleksander J.
