Abstract
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.
Claims18
A method for producing a connecting structure between two superconductors, comprising:
- providing magnesium diboride superconducting core wires, each enclosed within a normally conducting metal;
- forming exposed ends respectively on the superconducting core wires;
- mixing magnesium and boron with a substance that lowers a melting temperature of magnesium when mixed with magnesium, to produce a material mixture containing 1 to 20 wt % of the substance;
- bringing the exposed ends of the core wires into contact with the material mixture;
- and
- allowing the exposed ends of the core wires to react with the material mixture in situ at a reaction temperature corresponding to the lower melting temperature, to thereby form a magnesium diboride and a magnesium diboride connecting structure between the superconducting core wires.
