Abstract

PURPOSE:To produce a superconductive layer evenly throughout the whole length and to increase the mechanical strength by heat-treating a copper coverage layer formed on a core material and the elements of a mixing material layer including A element and B element to diffuse each other to produce a superconductor layer, in the manufacture of an A-B-Cu-O system oxide superconductive material. CONSTITUTION:In the manufacture of an oxide superconductive wire material of a general formula A-B-Cu-O (where A is one or more of the periodic table group IIIa elements such as Y, Sc, La, Yb, Er, Eu, Ho, and Dy, and B is one or more of the periodic table group IIa elements such as Be, Mg, Ca, Sr, and Ba), a copper coverage layer consisting of pure copper is formed on the surface of a core material consisting of a copper alloy including a deoxidizer of copper. Then at the outer surface of the copper coverage layer, a mixing material layer is formed to produce a laminate material. This mixing material layer includes A element and B element in a specific ratio. A heat treatment is applied to the laminate material to diffuse the elements of the layers each other to produce an oxide superconductive layer. In this case, the heat treatment is divided into two processes, the intermediate heat treatment and the final heat treatment.
