Title:
PRECURSOR WIRE FOR AN OXIDE SUPERCONDUCTING WIRE AND A METHOD FOR PRODUCING SAME, AND OXIDE SUPERCONDUCTING WIRE WHEREIN SAID PRECURSOR WIRE HAS BEEN USED
Document Type and Number:
WIPO Patent Application WO/2010/016302
Kind Code:
A1
Abstract:
Provided is a precursor wire for an oxide superconducting wire having a plurality of outer peripheral segments arranged in close proximity surrounding a central core on the inside of a first sheath of silver or silver alloy. The outer peripheral segments comprise single-core segments of arch-type cross section with a second sheath of silver or silver alloy covering a ribbon-like filament of an oxide superconductor precursor. A plurality of said outer peripheral segments are arranged in concentric layers in such a way that the wide surfaces of the outer peripheral segments surround said core.
