ABSTRACT:
A method of forming the superconducting body comprises forming a body comprised of a precursor deposit of an oxide superconductor on a substrate formed from a silver alloy comprised of a solute metal from the group consisting of yttrium, aluminum, lithium, zirconium, alkaline earths, lanthanides, and mixtures thereof in an effective amount to form oxide particles that increase the hardness of the substrate, and the balance silver. The body is annealed in an oxidizing atmosphere to form the oxide particles in the substrate, and the deposit into a continuous oxide superconductor.
