摘要： Disclosed herein is a method of manufacturing round wire using superconducting tape, including the steps of: slitting superconducting tape into superconducting tape strips; silver-coating the slit superconducting tape strips; laminating the silver-coated superconducting tape strips to form a superconducting tape laminate having a square cross-section; holding the superconducting tape laminate; heat-treating the fixed superconducting tape laminate to cause diffusion junction between silver; and copper-plating the heat-treated superconducting tape laminate to have a circular section. The method is advantageous in that, since it is formed by slitting, silver-coating and laminating conventional superconducting tape, its superconducting layer can be protected, and it has a circular cross-section, so that it can be easily joined and wound, with the result that it is expected that, like general copper wires, its application fields will be enlarged because it can be wound in a solenoid shape at the time of magnetic winding.

摘要： There is described a method of applying insulative coating on high temperature superconductors and low temperature superconductors from sol-gel solutions prepared from Zr or Zr with one of, Mg, Y, Ce, In and Sn based precursor materials. The solution is prepared with isopropanol as a solvent and acetyl acetone as a catalyst. The conductors are dipped into the solution and thereafter dried at a temperature effective to evaporate the solvent. Thereafter, heat treatment in the presence of oxygen is applied at a temperature sufficient to oxidize the precursors to result in a ceramic insulative coating on the conductor.

摘要： A composite member is prepared which comprises a core which will have a compound superconducting layer when heat-treated, and a stock for forming a stabilizing member made of copper and surrounding the core. The composite member is heat-treated in an oxidizing atmosphere, thus forming a copper-oxide thin layer on the surface of the stock. Thereafter, the composite member is heat-treated in a non-oxidizing atmosphere or in an atmosphere having an oxygen partial pressure which is too low to allow the forming of copper oxide. As a result, a compound superconducting wire is made which comprises a member including a compound superconductor, a diffusion-preventing layer made of oxide and surrounding the member, and a stabilizing member made of copper and surrounding the layer.

Several superconducting filaments are embedded in the matrix with these filaments being formed by a diffusion reaction between at least two elements. An aluminum jacket surrounds the matrix. A barrier layer formed from at least one intermetallic copper-aluminum compound is disposed between the aluminum jacket and the alloy matrix. The aluminum jacket may be formed by extrusion at an elevated temperature with the boundary layer between the aluminum jacket and the alloy matrix being concurrently formed by diffusion.
