A ceramic honeycomb structure comprised of at least two separate smaller ceramic honeycombs that have been bonded together by a cement comprised of inorganic fibers and a binding phase, wherein the smaller honeycombs and fibers are joined together by the binding phase, which is comprised of an amorphous glass of silicate, aluminate or alumino-silicate and the cement has at most about 5% by volume of other inorganic particles. The cement can be made in the absence of other inorganic and organic additives, while a slimming cement is achieved by cutting, for example, by mixing inorganic binders oppositely charged in water together in order to make a cement useful to apply to the honeycombs more Small to be cemented. |
