ABSTRACT:
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.
