Porous article and method of manufacturing the same

The present disclosure relates to porous ceramic articles and a method of making the same. The porous ceramic articles have a porosity (P) as a fraction in a range of about 0.3 to about 0.7; a permeability factor PQ>0.025, wherein PQ is (Kbulk)/(P·d502), Kbulk being bulk permeability in Darcy, an...

description The present disclosure relates to porous ceramic articles and a method of making the same. The porous ceramic articles have a porosity (P) as a fraction in a range of about 0.3 to about 0.7; a permeability factor PQ>0.025, wherein PQ is (Kbulk)/(P·d502), Kbulk being bulk permeability in Darcy, and d50 being the mean pore size in micrometers (μm); a tortuosity in a range of about 1.8 to 3; and a median pore size diameter d50 in a range of about 10 μm to about 35 μm. The porous ceramic articles can have an interconnected bead microstructure comprising beads and bead connections, PQ is directly proportional to bead size, and wherein in a random cross section through the body, the beads appear as globular portions.
