摘要： A method of producing a superconducting wire including an A-B-C-D system superconductor where the A includes an element of group IIIa of the Periodic Table, the B an element of group IIa of the Periodic Table, C copper, D oxygen. A plurality of filaments is selected from a copper alloy filament including: the A element, a copper alloy filament including the B element; a copper alloy filament including both the elements the A and the B; a first metallic filament having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a second metallic filament coated with an oxide layer; a copper filament containing the A element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a copper filament containing the B element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a third metallic filament containing the A element and coated with an oxide layer; a fourth metallic filament containing the B element and coated with an oxide layer; the first to fourth metallic filaments being substantially free of any component which provides an adverse effect on the production of the superconductor. The selected filaments are arranged for forming a superconductor element filaments bundle so that the superconductor is produced in a subsequent heat treatment. The bundle is drawn and then heated for producing the superconductor.

摘要： The invention relates to a method of making superconductive electric wire. The method involves the steps of: (a) preparing a tubular sheath made of silver or silver alloy, the cross sectional area of which is equal to or larger than 2/3 of the cross sectional area of a hollow space formed in the sheath; (b) preparing a green material comprising material elements of a superconductive material; (c) filling the hollow space of the sheath with the green material; (d) reducing the diameter of the sheath together with the green material contained therein; and (e) heat-treating the sheath and the green material in an oxygenous atmosphere, at a temperature 800.degree. to 1100.degree. C, for between 1 to 300 hours. The method is capable of producing a superconductive electric wire having a high critical temperature and a high critical electric current density.
