    Abstract: A method for manufacturing a honeycomb structure comprises providing an aqueous ceramic solution, providing a batch cross-link agent, mixing the agent with the solution, extruding the aqueous ceramic solution containing the cross-link agent into a honeycomb structure, and drying the honeycomb structure via a single drying step thereby forming a hardened, substantially water resistant, honeycomb structure. The method may further comprise addition of a ceramic surfactant to the aqueous ceramic solution, as well as plugging channels within the honeycomb structure with a plugging material comprising an aqueous ceramic solution that includes batch cross-link agents and ceramic surfactants therein. Also disclosed is a green body honeycomb article having a green honeycomb matrix containing a first ceramic batch compound of inorganic constituents, a first batch cross-link agent, and an aqueous vehicle wherein the matrix includes interconnected walls forming open-ended channels and a plugging material located in at least one of the open-ended channels.

    Abstract: Porous ceramic honeycomb articles for use as particulate filters and processes for making the same are described herein. The porous ceramic honeycomb articles include a fired cordierite body. The fired cordierite body has a microcrack parameter (Nb3) of about 0.05 to about 0.25 prior to exposure to a microcracking condition. After exposure to the microcracking condition, the fired cordierite body has a microcrack parameter (Nb3) at least 20% greater than the microcrack parameter prior to exposure to the microcracking condition. The fired cordierite body has a coefficient of thermal expansion (CTE) of about 7.0×10−7/° C. to about 15.0×10−7/° C. over from about 25° C. to about 800° C. prior to exposure to the microcracking condition and a coefficient of thermal expansion of about 1.0×10−7/° C. to about 10.0×10−7/° C. over from about 25° C. to about 800° C. after exposure to the microcracking condition. The microcrack parameter may include a thermal cycle or a chemical treatment.
