    摘要: This disclosure is directed to porous ceramic processing; and in particular to a method using selected pore forming materials to avoid high exotherms during the ceramic firing process, and the green bodies formed using the selected pore forming materials. The selected pore forming materials are homogeneous wax/non-ionic surfactant particles formed by a prilling process in which the wax is melted and the non-ionic surfactant is mixed into the wax prior to prilling. The disclosure is useful in the manufacture porous ceramic honeycomb bodies including ceramic honeycomb filter traps.

    摘要: A wall-flow honeycomb filter comprising a ceramic monolith (102) having a plurality of porous walls (114) formed therein. The plurality of porous walls (114) define a plurality of inlet cells (110) and a plurality of outlet cells (112) extending between an inlet end face (106) and an outlet end face (108) of the monolith. The inlet cells (110) are open at the inlet end face (106) and plugged at or near the outlet end face (108). The outlet cells (112) are open at the outlet end face (108) and plugged at or near the inlet end face (106). The monolith (102) has a ratio of a combined cross-sectional area of the inlet cells (110) to a combined cross-sectional area of the outlet cells (112) greater than 1. The monolith (102) has at least one inlet cell cluster (120) which contains an N x M group of inlet cells (110), N and M being integers greater than 1, each inlet cell cluster (120) consisting of a plurality of inlet cells (110) separated by inlet cluster walls (124).
