A ceramic precursor batch composition comprising inorganic ceramic-forming ingredients, a binder, an aqueous solvent and a heteroatom polyol agent. The heteroatom polyol agent can be represented by X(R) where X is at least one of S, N, and P, and R is at least two of CH3, CH2CH2OH, CH2CH2CH2OH, CH2(CHOH)CH3, C(CH2OH)1-3, CH2OH, CH(CH2OH)CHOH, C(O)(CHOH)1-4CH2OH, and CH2CH2CH2OCH3. The presence of the heteroatom polyol agent provides a composition with a lower viscosity and/or a greater batch stiffening temperature (Tonset) allowing for increased rates of extrusion. Methods for producing a ceramic honeycomb body using this ceramic precursor batch composition are also provided. |
