POROUS MULLITE BODIES HAVING IMPROVED THERMAL STABILITY
A porous ceramic composition having improved thermal stability is comprised of ceramic grains bonded together by grain boundary phase comprised of silica, yttrium and oxygen wherein the amount of alkali metals, alkaline earth metals and other transition metals not including rare earth metals is at most 2% by weight of the grain boundary phase.
