ABSTRACT:
A powder-in-tube method of producing an oxide superconduction wire is disclosed in which a preformed copper oxide superconducting powder is continuously filled into a tube precursor having a U shape cross-section formed from a long strip of metal material. The tube precursor is formed into a tube by bending and welding. The resulting tube is drawn to a reduced cross-section and further heated to sinter the packed powder to form the finished oxide superconducting wire.
