PROCESS FOR PRODUCING A CONNECTING STRUCTURE BETWEEN TWO SUPERCONDUCTORS AND STRUCTURE FOR CONNECTING TWO SUPERCONDUCTORS

摘要

A process produces a connecting structure between two superconductors, in particular magnesium diboride superconductors embodied as a superconducting core wire surrounded by normally conducting metal. A substance which reduces the melting point of magnesium is admixed to a substance mixture including magnesium and boron, and the exposed ends of the core wires are brought into contact with the substance mixture, which is caused to react in situ at a reaction temperature corresponding to the lower melting point to give magnesium diboride.
