ABSTRACT:
A high temperature superconducting wire and an improved process of making the same wherein a metal wire chosen from the group consisting of: Y; Sm; Eu; Gd; Dy; Ho; Er; Tm; Yb; and Lu is oxidized and the oxidized metal wire is then coated with molten barium-copper-oxide. The process allows high-quality superconducting wire to be easily and continuously fabricated.
