ABSTRACT:
A wire of ceramic superconductive material is produced by filling a metal tube with a powder of superconductive material, sealing the tube ends and drawing the filled, sealed tube through dies of progressively smaller size until a predetermined wire size is achieved and then heat treating the drawn wire to assure necessary crystallinity in the superconductor material.
