The invention features a superconducting conductor for use in a preselected fluid cryogen including a composite ceramic superconducting wire having an outer surface along its length; and a sealing structure hermetically surrounding the outer surface to prevent the cryogen from infiltrating into the wire and degrading its superconducting properties, even under pressurized conditions. The superconducting conductor can be used in superconducting cabling and coil applications. The sealing structure can be formed by laminating metallic tapes to the wire, encircling at least one metallic sheet around the outer surface of the wire, welding a plurality of metallic sheets to one another to encircle the outer surface of the wire, or forming a polymer coating completely covering the outer surface of the wire.

A method for joining high temperature superconducting components while minimizing critical current degradation is provided. The articles formed have critical currents that are at least 80 % of the critical current of the high temperature superconducting components. The invention further provides splicing geometries that facilitate wrapping joined components around a mandrel, tube or the like with minimal critical current degradation and without kinking or flexion of the joined components.
