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.

Porous ceramic processing using a co-prilled wax and non-ionic surfactant mixture

The disclosure provides a composition including a porous cordierite honeycomb body as defined herein having excellent strength, high thermal shock resistance, and reduced microcrack properties. The disclosure also provides methods of making and using the composition, for example, as a catalyst carrier.
