Verfahren zum Herstellen eines aus Niob und Kupfer und gegebenenfalls anderen elektrisch normalleitenden Metallen zusammengesetzten Leiters,insbesondere fuer supraleitende Kabel

摘要

A method of producing a conductor for a superconducting cable or the like is disclosed. The conductor is made up of at least niobium and copper of which the copper is an electrically normal-conducting metal. The method includes heating a niobium carrier to a temperature between 150 DEG and 800 DEG C in a vacuum having a residual gas pressure of at most 10<->4Torr, and evaporating copper unto the niobium carrier to form a tightly adhering copper layer thereon. If required, the conductor can be produced to include other electrically normal-conducting metals.
