Abstract
Provided is a superconducting apparatus, including a joint of superconducting wires having high electric conduction characteristics and a superconducting magnet or the like. The superconducting joint comprises a plurality of superconducting wires and a sinter which integrates the plurality of superconducting wires. Herein, at least any one of the superconducting wires is a MgBsuperconducting wire, the sinter contains MgB, and the sinter is compressed form the direction different from the direction toward which the superconducting wires protrude. Further, in order to form such a joint, a compression vessel provided with an opening used for introducing raw material powders to construct the sinter and another opening used for inserting the superconducting wires is utilized, and the openings are directed to different directions each other. Accordingly, MgBis filled in the sinter at high density, allowing the joint structure to have a good bonding property among particles.
