ABSTRACT:
Disclosed is a honeycomb ceramic article that exhibits a primary crystalline phase of cordierite having a coefficient of thermal expansion (CTE), wherein CTE<1.5×10−7/° C. over the temperature range of about 25° C. to about 800° C.; a total porosity, P, of at least 28%, a transverse I-ratio, IT, of less than 0.92; and a pore size distribution wherein at least 60% of the total pore volume is comprised of pores having diameters between 0.5 μm and 5.0 μm. Also provided is a ceramic honeycomb article comprising a phase of cordierite and exhibiting a mean CTE <1.0×10−7/° C. (from 25 to 800° C.) in at least one direction, and 28%≦P≦33%. Methods of manufacturing ceramic articles comprising the aforementioned cordierite compositions are also disclosed.
