Abstract

A superconducting joint that structurally binds a first superconducting segment to a second superconducting segment. The first and second superconducting segment each include corresponding areas containing a granular superconducting substance formed by a first element and a second element. The superconducting joint includes a solid non-superconducting binding formed from a source of the first element and a source of the second element combined to produce the granular superconducting substance around the solid non-superconducting binding to permit for the flow of superconducting current through the first superconducting segment and the second superconducting segment.
