Abstract

PURPOSE:To obtain a superconducting wire or tape with good quality and no open circuit or the like by melting a combination of a compound containing group II-A and group III-A elements and a compound containing copper, immersing a wire-shaped or tape-shaped metallic core material in this solution, lifting and quickly cooling it, then annealing it. CONSTITUTION:Rare earth metal elements such as Ca, Sr, Ba for II-A group elements of the periodic table and Sc, Y, La for III-A group elements are used, and oxide, carbonate, sulfate, nitrate, acetate or the like are used for a compound containing these elements and copper. A combination of them is melted in a conventional electric furnace or the like, a metallic core material is put in this solution, fine vibration is applied to remove air bubbles on the surface of the core material, it is wetted and stuck with the solution on the whole surface then lifted at the fixed speed. The lifted core material is quickly cooled in the air then put in the electric furnace at 800-950 deg.C and annealed for several hours and cooled. The productivity is thereby improved, a superconductor is fixed to the core material continuously and homogeneously, and a superconducting wire or tape with extremely excellent quality and no open circuit is obtained.
