ABSTRACT:
A glass-clad wire of ceramic superconductive material is produced by filling a glass-lined metal cylinder with a powder of superconductive material, sealing the cylinder ends and drawing the filled, sealed cylinder through dies of progressively smaller size until a predetermined wire size is achieved. The formed wire is then heat treated to assure necessary crystallinity in the superconductor material. Removal of the outer metal coating leaves a glass-clad superconductor wire.
