Abstract
There is provided a method of producing a protective metal coated or covered superconducting ceramic wire by applying a finely pulverized protective metal-dispersed polymeric resin onto the surface of a glass wire in amorphous state of metal oxides capable of being converted into superconductive ceramic, heating the wire to remove the polymeric resin therefrom to obtain the wire having a metal powder coating thereon, and heat-treating the wire to become superconductive. The coating is easily conducted without damaging the excellent productivity of the so-called melt-quenching and preform wire-drawing process for producing a superconducting ceramic wire.
