Abstract
PURPOSE: To readily form a connecting part having stable contact and high reliability in connecting a superconductive electric wire material, by using fine powder of a superconductive material of metallic oxide type having he same composition as that of the superconductive electric wire material.
CONSTITUTION: Stabilizing materials 2 (copper and alumina) at the tip parts of superconductive electric wire materials 1 and 1' to be connected are released and the top parts of opened core materials 3 are slantingly cut. Then, a sleeve 5 made of the same material as that of the stabilizing materials 2 is put on the vicinity of one of the superconductive electric wire materials 2, both the tip parts of the core materials 3 are placed opposite and slurry consisting of fine powder of a superconductive material of a metallic oxide having the same composition as that of the superconductive electric wire materials 1 and 1' are applied to gap between the core materials and the outer periphery. The slurry is coated, dried and burnt at about 850°C for about 2hr to give a superconductor 4. The superconductor is cooled after burning, the sleeve 5 is returned to the former position and the end part of the sleeve is integrated with the superconductive electric wire materials 1 and 1' by a soldering material 6. Consequently, the connecting part of the core materials 3 is covered with the sleeve 5, integrating strength is increased and the connecting part is thermally and electrically stabilized.
