Title:
SUPERCONDUCTING WIRES AND METHODS OF MAKING THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/175064
Kind Code:
A3
Abstract:
Disclosed herein are superconducting wires. The superconducting wires can comprise a metallic matrix and at least one continuous subelement embedded in the matrix. Each subelement can comprise a non-superconducting core, a superconducting layer coaxially disposed around the non-superconducting core, and a barrier layer coaxially disposed around the superconducting layer. The superconducting layer can comprise a plurality of Nb3Sn grains stabilized by metal oxide particulates disposed therein. The Nb3Sn grains can have an average grain size of from 5 nm to 90 nm (for example, from 15 nm to 30 nm). The superconducting wire can have a high-field critical current density (J
c
) of at least 5,000 A/mm2 at a temperature of 4.2 K in a magnetic field of 12 T. Also described are superconducting wire precursors that can be heat treated to prepare superconducting wires, as well as methods of making superconducting wires.
