Abstract
PURPOSE:To obtain an oxide system superconductive wire material of a good superconductivity and a high mechanical strength by forming a coverage layer of pure copper on the surface of a base member, oxidizing it, then forming a mixture material layer including specific compounds on the surface, and applying a heat treatment. CONSTITUTION:On the surface of a base member 1 formed in a tape, a coverage layer 2 of pure copper is formed. As the material of the base member 1, a metal material of a good antiacid property such as Ni can be used. Then, an oxidization process is applied to form a copper oxide film 3 on the surface of the coverage layer 2. After that, a mixture material layer 4 of A element (a periodic table IIIa group metal) and B element (an alkaline earth metal) is formed on the surface. The mixture material layer 4 is formed by making a mixture powder of an yttrium oxide and a barium oxide, for example, mixed at a specific ratio into a sol in ethanol, and the base member 1 is passed in the sol continuously to attach the sol material to the copper oxide film 3. Then, it is heat-treated in an oxidation atmosphere at 600 to 1000 deg.C for about one to several dozens hours. In such a series of operations, a tape-form superconductive wire material 6 in which a superconductor layer 5 including the Y-Ba-Cu-O system superconductor is formed can be produced.
