Title:
OXIDE SUPERCONDUCTING WIRE ROD, SUPERCONDUCTING STRUCTURE, METHOD FOR MANUFACTURING OXIDE SUPERCONDUCTING WIRE ROD, SUPERCONDUCTING CABLE, SUPERCONDUCTING MAGNET, AND PRODUCT COMPRISING SUPERCONDUCTING MAGNET
Document Type and Number:
WIPO Patent Application WO/2008/065781
Kind Code:
A1
Abstract:
This invention provides a tape-like oxide superconducting wire rod comprising
a plurality of filaments containing a Bi-2223-type oxide superconductor embedded
in a matrix. The sectional area in a cross section perpendicular to the longitudinal
direction of the oxide superconducting wire rod is not more than 0.5 mm2.
In the cross section of the oxide superconducting wire rod, the average sectional
area per filament can be brought to not less than 0.2% and not more than 6% of the
sectional area of the oxide superconducting wire rod to enhance the critical
current density and, at the same time, to lower the alternating-current loss.
There are also provided a superconducting structure, a method of manufacturing
the oxide superconducting wire rod, a superconducting cable, a superconducting
magnet, and a product comprising the superconducting magnet.
