    摘要: The present invention provides a high-throughput system for the ex-situ formation of a superconducting thin film, such as rare-earth-barium-copper-oxide (REBCO), atop a continuous length of buffered metal substrate tape by heating a buffered metal substrate tape coated with precursors of REBCO These precursors, when heated and introduced to water vapor within a process chamber, decompose to form a functional superconducting thin film epitaxial to the buffer layer. A chamber such as a metalorganic chemical vapor deposition (MOCVD) reactor having showerhead and substrate heater assemblies designed for the creation of a long and wide deposition zone is well suited for use in the process the system. The chamber could be of cold-wall type where the walls are not heated or could of hot-wall type where the walls are heated.

    摘要: An oxide superconducting wire is obtained by performing plastic working and heat treatment of a metal pipe which is filled up with raw material powder of an oxide superconductor. In the plastic working step, the metal pipe is subjected to flat working so that the raw material powder flows in the longitudinal direction as well as the cross direction in the metal pipe. In this case, a draft of at least 80% and not more than 98% is selected in the flat working step, to further promote the cross-directional flow of the raw material powder, thereby further improving density of the raw material powder. Thus, the as-formed oxide superconducting wire exhibits higher critical current density.

    摘要: High-Tc superconducting ceramic oxide products and macroscopic and microscopic methods for making such high-Tc superconducting products. Completely sealed high-Tc superconducting ceramic oxide provides are made by a macroscopic process including the steps of pressing a superconducting ceramic oxide powder into a hollow body of a material inert to oxygen; heat treating the superconducting ceramic oxide powder packed body under conditions sufficient to sinter the ceramic oxide powder; and then sealing any openings of the body. Optionally, a waveform or multiple pulses of alternate magnetic filed can be applied during the heat treatment. The microscopic method of producing a high-Tc superconducting ceramic oxide product includes the steps of making a high-Tc superconducting ceramic oxide thin film; optionally sintering the deposited thin film in a magnetic filed; and removing partial oxygen content of the thin film by a scanning tunneling electron treatment machine to form a microscopic insulation layer between two high-Tc superconducting domains of the thin film.

    摘要: A layered oxide superconductor prepared by depositing a superconductor precursor powder on a continuous length of a first substrate ribbon. A continuous length of a second substrate ribbon is overlaid on the first substrate ribbon. Sufficient pressure is applied to form a bound layered superconductor precursor powder between the first substrate ribbon and the second substrate ribbon. The layered superconductor precursor is then heat treated to establish the oxide superconducting phase. The layered oxide superconductor has a smooth interface between the substrate and the oxide superconductor.

    摘要: The present invention provides a method of producing high-strength and high-conductance copper and silver materials comprising the steps of combining a predetermined ratio of the copper with the silver to produce a composite material, and melt spinning the composite material to produce a ribbon of copper and silver. The ribbon of copper and silver is heated in a hydrogen atmosphere, and thereafter die pressed into a slug. The slug then is placed into a high-purity copper vessel and the vessel is sealed with an electron beam. The vessel and slug then are extruded into wire form using a cold hydrostatic extrusion process.
