Abstract
A porous ceramic body including a major phase of beta-spodumene and a minor phase of mullite, the aggregate composition of a batch in weight percents of LiAlSi2O6, SiO2, and Al6Si2O13 are as defined herein. Also disclosed is a method for making a porous ceramic article is and includes: mixing inorganic batch ingredients including sources of silica, alumina, and lithia, with a liquid and an organic binder to form a plasticized batch mixture; forming a green body; and heating to the porous ceramic article, comprised of a major phase of beta-spodumene and a minor phase of mullite.
