Method of producing superconducting wire.

摘要

The present invention relates to a method of producing a superconducting wire, in particular to a novel method of producing a ceramics superconducting wire. The ceramics superconductor has been obtained by sintering metallic powders containing raw material ingredients but the resulting ceramics superconductor has been remarkably fragile, wanting in ductility, and inferior in bending strength, so that it has shown a problem in that it can not be turned into a long wire. The present invention was achieved in order to solve the above described problem and can provide a long superconducting wire by continuously coating a long substrate with raw material powders composing the ceramics superconducting wire and then sintering it in a temperature range in which a superconducting layer can be formed.
