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.
