ABSTRACT:
A superconductive substance is formed into fine wires readily without producing surface defects on the wires and correctly with a predetermined even diametric thickness. Highly refractory metallic core is heated to a predetermined temperature higher than the eutectic point of powders which constitute the superconductive substance, and passed through said powders whereby the powders which make contact with the core melt and adhere to the core with a predetermined uniform thickness, forming a fine wire made from the superconductive substance.
