METHOD FOR INCREASING THE RESISTANCE OF A POROUS CERAMIC BODY, POROUS CERAMIC BODY AND FILTER 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. form the porous ceramic body. The porous ceramic body has a boron-containing oxide glassy phase in at least a portion of the ceramic grains of the porous ceramic body. |
