Abstract
The present invention relates, generally, to a self-supporting porous ceramic composite body and to methods for producing such articles to net or near net shape, which bodies exhibit superior thermal and mechanical properties. The invention also relates to the manufacture of ceramic-metal or ceramic-ceramic macrocomposite bodies which have the porous ceramic articles incorporated therein or thereon.
