  • Method of repairing porous ceramic bodies and ceramic composition for same
    Patent number: 5980980
    Abstract: A ceramic composition for the repair of porous ceramic bodies comprises a ceramic material having cations which are reactive with phosphate ions, a source of reactive phosphate ions, and filler. An aqueous slurry of the ceramic composition is prepared and applied to the damaged region of a porous ceramic body. The slurry mixture is dried within the damaged region of the porous ceramic body and heated to bind the mixture together and to bond the mixture to the porous ceramic body within the damaged region. The method of the invention allows for the in situ repair of ceramic materials without removing them from their supporting structure and can be used in the repair of ceramic tiles for spacecraft and aircraft.
