| 摘要 |
The invention concerns a method for the manufacture of a superconductor which comprises a superconductive, intermetallic compound including at least two elements. A ductile component of at least one element of the compound is brought into contact with a ductile carrier metal bearing the other elements of the compound. The structure so obtained is heat-treated in a vapor formed over a separate melt of the elements found in the carrier metal in such a manner that the intermetallic compound is formed through reaction of the vapor, diffusing through the carrier metal, with the ductile component. The heat treatment applied until the ductile components and the other elements reach the same temperature is performed in a vacuum with a residual maximum gas pressure of 10<->2 Torr or in an inert gas at a maximum gas pressure of 500 Torr.
