Claim 0:
1. A ceramic body, comprising:
% P≥50%, wherein % P is average bulk porosity by volume;
df≤0.36, wherein df is (d50-d10)/d50;
a combined weight percentage of crystalline phases containing cordierite and indialite of at least 85 wt %;
up to 10 wt % of a crystalline phase comprising a pseudobrookite structure,
wherein the ceramic body contains, as expressed in weight percent on an oxide basis, either:
1% wt % to 11% wt % titania and 89% wt % to 99% wt % MgO, Al2O3, and SiO2 that have relative weight ratios of MgO:Al2O3:SiO2 within the field defined by 15.6:34.0:50.4, 12.6:34.0:53.4, 13.9:30.7:55.4, and 16.9:30.7:52.4, or
2.5% to 11% titania and 89% wt % to 97.5% wt % MgO, Al2O3, and SiO2 that have relative weight ratios of MgO:Al2O3:SiO2 within the field defined by 15.6:34.0:50.4, 12.6:34.0:53.4, 12.0:35.7:52.3, and 15.0:35.7:49.3.
