摘要： A process for producing a superconducting article having a layer of compound oxide of quasi-perovskite type oxide crystal structure by electrodeposition technique. The process is characterized by dispersing a material powder in a liquid containing a carrier, driving ionized material particles towards a substrate by applying a direct current between a substrate and a counter electrode, and then sintering a thin layer of powders deposited on the substrate to convert the deposited powders to a superconducting compound oxide.

摘要： A thin film of a preselected compound having a large area is continuously produced on a substrate by depositing elements constituting the preselected compound from a target member onto the surface of a substrate by sputtering, comprising the steps of:rotating a first target member having a flat surface disposed around an axis which crosses the surface and comprising elements of the preselected compound so that a first part of the surface of target member is positioned at a first sputtering position and another part of the first target member is positioned at a second sputtering position,at the first position, sputtering at least one second target comprising at least one element of the preselected compound which is easily sputtered from the first target member so as to supply the deficient element to the first target member, andat the second position, sputtering the elements from the first target member so as to deposit them on the surface of said substrate while continuously supplying the substrate so that a part of the substrate is positioned in the path of the sputtered elements,whereby the elementary composition of the first target member at the second position is adjusted to the preselected composition.

摘要： The present invention relates to a method of producing a superconducting composite wire. The method comprises forming a continuously supplied metal or metal alloy strip into a flume-shaped strip. A ceramic copper oxide superconducting powder material is filled in the interior of the flume-shaped strip. The flume-shaped strip is rolled such that a first edge of the strip approaches a second edge of the strip to form a tubing having a gap between the first and second edges and also having the powder material enveloped therein. The gap allows free access of oxygen to the powder material during a subsequent sintering step. The powder material is then sintered at a temperature of between 0 and 100.degree. C. less than the lowest melting point of any constituent of the material. The strip enveloping the sintered material is then deformed to a reduced cross-section and subjected to a heat treatment.
