    摘要： Disclosed are: a tape base for a superconducting wire, which simplifies the intermediate layer and thus enables production of a superconducting wire at lower cost, and which is capable of improving the characteristics (such as electrical conduction and handling properties) of a superconducting wire; and a superconducting wire. Specifically disclosed is a tape base for a superconducting wire, which is obtained by forming an intermediate layer on a metal substrate. The tape base for a superconducting wire is characterized in that a biaxially oriented layer of the intermediate layer is configured of a niobium monoxide (NbO) layer that is formed by depositing vapor deposition particles from a vapor deposition source on a film formation surface.

    摘要： A superconducting wire includes first and second superconducting layers disposed on one or more substrates in stacked relationship, the first superconducting layer comprising a high temperature superconducting oxide of a first composition and the second superconducting layer comprising a high temperature superconducting layer of a second composition, wherein the first and second compositions are different. The first superconductor layer optionally includes a high temperature superconductor composition selected to provide enhanced critical current (lc(c)) in the presence of magnetic fields perpendicular to surface of the superconducting layer (H//c). The second superconductor layer optionally includes a high temperature superconductor composition selected to provide enhanced critical current (Ic) in the presence of magnetic fields parallel to surface of the superconducting layer (H//ab).

    摘要： A method of producing a superconductive wire material comprises a step of filling in a metal pipe raw material powder formed from an oxide superconductive body or raw material powder formed from a precursor that turns to an oxide superconductive body by heat treatment, a step of heating the metal pipe filled with the raw material powder to a temperature between 400°C or more and 800°C or less, a step of reducing pressure in the heated metal pipe to 100 Pa or less, a step of sealing the opening at an end portion of the metal pipe with the pressure reduced, and a step of drawing the metal pipe in which the raw material powder is sealed. When filling density of the raw material powder is between 10% or more and 40% or less, a critical current density can be improved by sufficiently removing gas inside the metal pipe.

    摘要： A method is described for the production of superconductive wires based on hollow filaments made of MgB 2 , which comprises: a) the formation of a composite billet by means of the coaxial insertion in a tubular metallic container of a cylindrical bar made of metallic magnesium and amorphous boron powder in the interspace between the container and bar, said powder being pressed between the metallic container and the magnesium bar, in such a quantity that the weight ratio magnesium/boron is higher than 1.2; b) at least one plastic deformation treatment of the composite billet thus obtained until a wire with a prefixed diameter is obtained, with the subsequent winding of the wire onto a support; c) a thermal treatment of the filament product thus obtained, at a temperature ranging from 700°C to 950°C for a time ranging from 15 minutes to three hours.
