Methods of pre-densifying a metal wire containing superconductor materials are provided. Superconductor materials containing the pre-densified wires also are provided. The wires may be pre-densified by subjecting a metal wire that includes one or more filament cavities in which a superconductor precursor powder is disposed to a temperature and a first pressure for a time sufficient to densify the superconductor precursor powder to form a pre-densified metal wire, wherein the temperature is less than the melting point of the superconductor precursor powder, and the first pressure is sufficient, at the temperature, to compress at least a portion of the metal wire.

Densified superconductor materials and methods

The present invention provides a system and method for producing superconducting joints between superconductive segments of a Bi-2212 high-temperature superconducting (HTS) conductor, thereby eliminating the heat generating resistive joints that are commonly known in the art for connecting two or more smaller Bi-2212 conductive segments to create an Bi-2212 conductor of adequate length.
