| abstract |
A process is provided for the production of superconducting wires, ribbons, tapes, fibers and the like including the steps of forming an amorphous metal alloy containing at least one of scandium, yttrium or the rare earths; copper; and at least one alkaline earth as an elongated body, and reacting the amorphous metal alloy with oxygen at a temperature below the crystallization temperature of the alloy to form a sheath of superconducting oxide exterior to a core of amorphous metal alloy. Included in the invention are the elongated bodies thus produced and superconductor devices fabricated from said bodies. |
