摘要： A method of producing a superconductor including a superconductive oxide. At least one material is pressed for forming a filling material, the at least one material being selected from the group consisting of a starting material powder of the superconductive oxide, a powder of the superconductive oxide and a compact made of the starting material powder and/or the superconductive oxide powder, for forming a filling material. The filling material is charged into a metallic pipe to form a preform. The preform is moved along an axis thereof. During moving, the preform is swaged perpendicularly to the axis thereof to form a composite having a metallic sheath, made of the metallic pipe, and a core sheathed with the metallic sheath. The core of the composite is heated for producing the superconductive oxide.

摘要： A method of fabricating a superconductive electrical conductor of Nb.sub.3 Sn type comprises a step of covering an elongated core member made of Nb with a covering member made of a third element selected from the group consisting of Ti, Ta, In, Hf, Al and Si. The core member covered with the covering member is covered with a tubular matrix made of a Cu-Sn alloy or a combination of Cu with Sn to form a composite wire element. Such wire elements are assembled in a tubular matrix made of a Cu-Sn alloy, Cu or a combination of Cu with Sn and reduced in diameter to form a multi-core composite wire element having a desired diameter. The assembling and reducing processing is effected at least one to form a multi-core composite wire which is then subjected to a diffusion heat-treatment to form an intermetallic compound of Nb.sub.3 Sn and the third element in the peripheral portion of the core member.
