    摘要: A wall-flow filter having a honeycomb body being composed of a plurality of end-plugged cell channels defined by an array of interconnecting and intersecting porous walls, the cell channels extending between end faces of the honeycomb body, the cell channels having fillets at each corner. An extrusion die for making the honeycomb body is described.

    摘要: Porous, non-microcracked cordierite ceramic bodies having high strength, high strain tolerance, and high thermal shock resistance are produced from cordierite powder batch mixtures of controlled powder particle size fired according to a schedule that prevents objectionable cordierite grain growth, maintaining a small cordierite crystalline domain size in order to minimize or prevent microcracking in the product.

    摘要: 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.
