Joining of high-temperature oxide superconductors.

摘要

The present invention provides a method for joining of high-temperature oxide superconductors (1) per se or a high-temperature oxide superconductor (1) and other conductive material (5) through a very simple process. According to this method, the joining is carried out by using an alloy (2) comprising 0.1-90% by weight of at least one divalent metallic element and the balance as a brazing material and heating and melting the brazing material. The resulting joined body has a joint low in resistance. The divalent metallic element of the alloy is preferably an element of Group IIA or IIB of the Periodic Table or a transition metal.
