Abstract
A porous ceramic honeycomb article comprising a honeycomb body formed from cordierite ceramic, wherein the honeycomb body has a porosity P %≧55% and a cell channel density CD ≧150 cpsi. The porous channel walls have a wall thickness T, wherein (11+(300−CD)*0.03)≧T≧(8+(300−CD)*0.02), a median pore size ≦20 microns, and a pore size distribution with a d-factor of ≦0.35. The honeycomb body has a specific pore volume of VP≦0.22. The porous ceramic honeycomb article exhibits a coated pressure drop increase of ≦8 kPa at a flow rate of 26.5 cubic feet per minute when coated with 100 g/L of a washcoat catalyst and loaded with 5 g/L of soot.
