    摘要: Disclosed are ceramic honeycomb articles which are composed predominately of a crystalline phase cordierite composition. The porous cordierite ceramic honeycomb articles has a plurality of cell channels and intersecting porous walls and possess a microstructure characterized by a pore size distribution wherein greater than or equal to 75% of the pore size distribution of the porosity of the porous walls, by volume, have a pore diameter (dv) wherein dv
