Abstract

Cordierite ceramic articles with high volume percent porosities of at least 64% but less than 80% have controlled median pore sizes and mean coefficients of thermal expansion that impart substantially improved modulus of rupture strengths (MOR) and thermal shock resistance (TSR) to the ceramic articles.
