ABSTRACT:
A porous ceramic body having increased strength is formed by exposing a porous ceramic body to a source of boron and heating the porous body to a sufficient temperature in an oxygen containing atmosphere to form the porous ceramic body. The porous ceramic body has a boron containing oxide glassy phase on at least a portion of the ceramic grains of the porous ceramic body.
