摘要： A method of manufacturing a fine multifilamentary Nb-Ti based superconducting wire was disclosed, which comprises a first step of processing an alloy consisting essentially of 10 to 50 atomic % of niobium, 40 to 75 atomic % of titanium and no higher than 30 atomic % of least one element selected from a group consisting of hafnium, tantalum and tungsten to form an alloy wire, a second step of covering said alloy wire with a stabilizer, cold drawing the resultant wire, bundling a plurality of a stabilizer-clad wires thus obtained, covering the bundle of wires with a stabilizer, and extruding and cold drawing the resultant bundled wire to thereby form a multifilamentary wire, and a third step of thermally treating the resultant multifilamentary wire at a temperature of 250 to 600°C and drawing the resultant treated multifilamentary wire to a reduction rate of 30 to 99.9 %. The third step is carried out more than once.

摘要： A powder having a predetermined composition is filled in a tube. The tube is drawn to obtain a wire and the wire is rolled to obtain a tape-like starting body (7). Then, a laser beam (3) is irradiated on the part of the tape to heat and melt the part of the tape. The starting body (7) is rapidly heated and then cooled, thereby the part of the starting body is melted and solidified to form a compound superconductor layer (12).

摘要： A high-Tc oxide superconductor including Bi, Sr, Ca, Cu, O and at least one of Pb and Al, with a high critical temperature than that of liquid nitrogen. A method for producing the high-Tc oxide superconductor is also disclosed, in which Bi₂O₃, SrCO₃, CaCO₃, CuO and PbO or Al₂O₃ powders are mixed calcined, ground, cold-pressed and sintered. The calcined mixture may be melted and annealed to obtain a tape-form superconductor.
