Abstract:
1. A cordierite ceramic article having at least 64% porosity and less than 80% porosity, a median pore diameter (d 50 ) of at least 10 μm and not more than 45 μm, a mean CTE (25-800° C.) in the axial direction wherein 0.5(d 50 -24.0)<CTE (25-800° C.)<0.5(d 50 -5.0) wherein d 50 is expressed in micrometers and CTE (25-800° C.) is expressed in units of 10 −7 /° C., and a modulus of rupture MOR flexural strength of at least 500 psi as measured on a non-cellular rod or bar, or a ratio of modulus of rupture strength /closed frontal area MOR/CFA of at least 500 psi as measured on a cellular bar.
