摘要： The present invention describes a high porosity (% P≧45%), refractory, ceramic article comprising a cordierite ceramic phase and at least about 0.1 wt. % of a rare earth oxide, such as yttrium oxide or lanthanum oxide. When compared to typical high-porosity cordierite articles, the articles of the present invention may exhibit relatively high strength, relatively low microcracking, relatively high strain tolerance (MOR/E), and/or relatively high thermal shock resistance (TSP).
