    摘要: Metal ion conducting ceramic materials are disclosed having characteristics of high ion conductivity for certain alkali and monovalent metal ions at low temperatures, high selectivity for the metal ions, good current efficiency and stability in water and corrosive media under static and electrochemical conditions. The metal ion conducting ceramic materials are fabricated to be deficient in the metal ion. One general formulation of the metal ion conducting ceramic materials is Me1+x+y−zMIIIyMIV2−ySixP3−xO12−z/2, wherein Me is Na+, Li+, K+, Rb+, Cs+, Ag+, or mixtures thereof, 2.0≦x≦2.4, 0.0≦y≦1.0, and 0.05≦z≦0.9, where MIII is Al3+, Ga3+, Cr3+, Sc3+, Fe3+, In3+, Yb3+, Y3+, or mixtures thereof and MIV is Ti4+, Zr4+, Hf4+, or mixtures thereof.

    摘要: A method of sintering large refractory ceramic articles is disclosed. The method includes supporting a green refractory body on a plurality of support plates, the support plates in turn being supported by a plurality of support members having arcuate upper and lower surfaces. A setter material is disposed between the green refractory body to be sintered and the support plates. As the refractory body is sintered, the density of the article increases. Concurrently, the dimensions of the body decrease, which shrinkage, unless otherwise accommodated, may cause fracture of the body. The support plates and the structure of the support members, move to prevent the development of detrimental stresses in the refractory body as it sinters.

    摘要: The invention relates to a method of manufacturing compounds of the Monazite type, doped or not doped with actinides, to a method of packaging radioactive waste, high in actinides and in lanthanides by incorporating this waste in a confining matrix based on Monazite, and to a block for the packaging of radioactive waste that includes a Monazite matrix containing the radioactive elements. This method includes mixing, in the solid phase, reactants comprising an inactive compound of the lanthanide metaphosphate type Ln (PO.sub.3).sub.3 and one or more lanthanide oxides and/or one or more compounds capable of reacting with this oxide or these oxides during a thermal sintering process; the shaping of the mixture thus obtained, and the reaction sintering of said formed mixture, as a result of which a Monazite or a compound of the Monazite type is obtained.

    摘要: 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.
