Abstract
Processes for manufacturing porous ceramic honeycomb articles are disclosed. The processes include mixing a batch of inorganic components with processing aids to form a plasticized batch. The batch of inorganic components include talc having d≦10 μm, a silica-forming source having d≦20 μm, an alumina-forming source having a median particle diameter dof less than or equal to 10.0 μm, and a pore former having d≦20 μm. The plasticized batch is formed into a green honeycomb article and fired under conditions effective to form a porous ceramic honeycomb article comprising a cordierite crystal phase and having a microcrack parameter (Nb) of from about 0.05 to about 0.25. After firing, the green honeycomb article the porous ceramic honeycomb article is exposed to a microcracking condition, which increases the microcrack parameter (Nb) by at least 20%.
