The present disclosure relates to porous ceramic articles and methods of making the same. Porous ceramic articles have a porosity (P) as a proportion in the range of about 0.3 to about 0.7, permeability factor PQ> 0.025, where PQ is (K bulk ) / (P · d 50 2 ), K bulk is the bulk permeability of Darcy, d 50 is the average pore size in micrometers (μm)), and a twist degree in the range of about 1.8 to 3; It has a median pore size diameter d 50 in the range of 10 μm to about 35 μm. The porous ceramic article can have an interconnected bead microstructure including beads and bead connecting portions, where PQ is directly proportional to the bead size, and in a random cross section through the body, the beads are as spherical portions. appear. |
