Producing strong, electroconductive joint between high temperature superconductor parts, e.g. for magnets, current limiters or superconductor bearings, comprises using a bonding mixture without external pressure application

摘要

Strong, electrically conductive joint production between high temperature superconductors, using a bonding mixture of superconducting or metallic powder and binder solution without external pressure application, is new. Mechanically strong, electrically conductive joint is produced between high temperature superconductors comprises: (a) applying a mixture of superconducting or metallic powder, binder and binder solvent onto the joint faces of the superconductor parts; and (b) briefly pressing the parts together without external pressure application. Preferred Features: The powder material is selected from Ag, Au, Cu, their alloys and other metals and alloys, which do not affect the superconducting properties, or mixtures of REBa2Cu3Ox/RE'BaCuOx/Pt/Ce/Ag/L1/L2 (L1 = BaCuOx and L2 = Ba3Cu5Ox), the material having a lower eutectic or peritectic temperature than that of the parts to be joined.
