A ceramic honeycomb structure comprising at least two separate smaller ceramic honeycombs bonded together by an adhesive comprising an inorganic fiber and a binder phase, wherein the smaller honeycomb and fiber are silicate, aluminate or alumino A ceramic honeycomb structure bonded together by a binder phase consisting of silicate; The fibers have a multimodal length distribution with some fibers having a maximum length of 1000 microns and others having a length greater than 1 mm. The adhesive composition can be sheared down, for example, by mixing and mixing together inorganic binders of opposite charge in water to make a useful adhesive composition for application to smaller honeycombs to be bonded. It can be made in the absence of other inorganic and organic additives while realizing an adhesive. |
