Title:

SUPERCONDUCTING WIRE AND SUPERCONDUCTING COIL

Document Type and Number:

WIPO Patent Application WO/2016/111159

Kind Code:

A1

Abstract:

The present invention is a superconducting wire comprising a wire made from a superconductor and a superconduction stabilizer material disposed so as to contact the wire. The superconduction stabilizer material comprises a copper material containing a total of 3 to 400 ppm by mass of one or more additional elements selected from among Ca, Sr, Ba, and rare earth elements, with Cu and inevitable impurities as the remainder. The total concentration of the inevitable impurities other than the gas components O, H, C, N and S is 5 to 100 ppm by mass.
