A process for the preparation of a wire made of superconducting oxide wire and thus produced.

摘要

A method of producing an oxide superconducing wire. A non-oxidizing metal layer is formed between an oxide superconducting material and an oxidizing metal support in order to prevent oxygen from being taken away from the oxide superconducting material by the oxidizing metal support during a subsequent heat treatment for producing an oxide superconductor to thereby obtaining a wire composite. The wire composite is then heated to produce the oxide superconductor.
