Process for the production of multi-layer composite conductors containing high transition temperature ceramic superconductors

摘要

Process for the production of multi-layer composite conductor containing high transition temperature ceramic superconductor, comprising a first step in which a single electrically conductive thin metal sheet (3), is cut into the desired shape and it is then folded, through mechanical deformation, in order to form flat bellows, a second step in which the thin bellows folds (3) are filled with a superconductive ceramic powder (4), and finally a third step in which said flat bellows, containing the superconductive ceramic powder (4) inside of them, undergo a mono-axial pressing in such a way so as to bring the sides of the flat bellows one next to the other, thus enclosing within them the superconductive ceramic powder (4).
