Abstract: 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.

Abstract: A two step method for preparing a filler composition, the filler composition useful to prepare a nanocomposite polymer and an epoxy nanocomposite coating. First, disperse a water dispersible filler material in a liquid comprising water, but without any added intercalation agent, to form a dispersion. Second, replace at least a portion of the water of the liquid with an organic solvent so that the water concentration of the liquid is less than six percent by weight to form the filler composition, the average size of at least one dimension of the filler material being less than two hundred nanometers upon examination by transmission electron microscopy of a representative freeze dried sample of the dispersion of the first step. A nanocomposite polymer can be prepared by mixing the filler composition with one or more polymer, polymer component, monomer or prepolymer to produce a polymer containing the filler composition.
