  • Method for increasing the strength of porous ceramic bodies and bodies made therefrom
    Patent number: 7381681
    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.
