Patent ID: 8759240

Claim:
A method for reducing pore size variability in ceramic bodies and/or reducing process variability in making ceramic bodies, the method comprising: selecting as inorganic batch components for use in making the ceramic bodies: (a) at least one silica source having a particle size distribution with an sD breadth of about 2 or less, and a median particle size (sd 50 ) ranging from about 5 μm to 250 μm; and (b) at least one source chosen from alumina sources, titania sources, magnesium sources, strontium sources, or calcium sources; wherein the median particle size (sd 50 ) of the silica source varies by about ±4 μm or less; wherein the at least one silica source has an sd 10 that varies by about ±0.5 μm or less; and wherein the at least one silica source has an sd 90 that varies by about ±10 μm or less.
