Abstract: The invention provides for A method for producing pure phase strontium ruthenium oxide films, the method comprising solubilizing ruthenium-containing and strontium-containing compounds to create a mixture; subjecting the mixture to a first temperature above that necessary for forming RuO2 while simultaneously preventing formation of RuO2; maintaining the first temperature for a time to remove organic compounds from the mixture, thereby forming a substantially dry film; and subjecting the film to a second temperature for time sufficient to crystallize the film. Also provided is pure phase material comprising strontium ruthenium oxide wherein the material contains no RuO2.

Abstract: A thermal method of making a hydrogen permeable composition is disclosed. A mixture of metal oxide powder and ceramic oxide powder and optionally a pore former is formed and pressed to form an article. The article is dried at elevated temperatures and then sintered in a reducing atmosphere to provide a dense hydrogen permeable portion near the surface of the sintered mixture. The dense hydrogen permeable portion has a higher initial concentration of metal than the remainder of the sintered mixture and is present in the range of from about 20 to about 80 percent by volume of the dense hydrogen permeable portion.

Abstract: A method of making a hydrogen permeable in which a colloid suspension of metal powder and ceramic oxide powder dispersed in an organic carrier is contacted with a porous ceramic substrate to deposit a thin film of the colloid suspension on the substrate. The film is then dried and sintered to provide a two part membrane adhered to the porous ceramic substrate. The two part membrane has a metal powder part of one or more of Ni, Pd, Pd alloys, Nb, Ta, Zr, V or mixtures thereof, and an oxide part of one or more of yttria stabilized zirconia, shrinkable alumina, suitably doped cerates, titanates, zirconates of barium or strotium or mixtures thereof, wherein the metal powder part is present in the range of from about 20 to about 80 percent by volume of the two-part membrane.

The two part membrane has a metal powder part and a ceramic oxide part, with the metal powder part being Ni, Pd, Pd alloys, Nb, Ta, Zr, V or mixtures thereof. The oxide part is yttria stabilized zirconia, shrinkable alumina, suitably doped cerates, titanate, zirconates of barium or strontium or mixtures thereof, and the hydrogen flux is at least 20 cm3 per minute-cm2 at 500° C. in a 100% hydrogen atmosphere. A paste method of forming the composition is disclosed. A method of extracting hydrogen from a gas is also disclosed.

Abstract: A layered composition of a Cu-containing ceramic superconductor layer and a Ag-containing layer having between about 0.1 and about 0.3 atom percent Cu. The ceramic superconductor may be in contact with the Ag-containing copper doped layer which may be one or more of a substrate, a stabilizer or a sheath. Oxide superconductors are preferred.
