SUPERCONDUCTING JOINT USING DETACHED REBCO Russian patent published in 2020 - IPC H01R39/02 

FIELD: technological processes.

SUBSTANCE: invention can be used to form superconducting joints between rare-earth element complex oxides. Essence of invention consists in that method of forming superconducting joint between ReBCO tapes includes providing two or more ReBCO tapes, each of which has open ReBCO domain; providing a bridge comprising an open ReBCO layer and a silver protective coating on the ReBCO open layer; each open connection with the open area ReBCO bridge ReBCO layer by heating to a first temperature (T1) in an environment where the oxygen partial pressure is sufficiently low that the minimum temperature (T_J) docking ReBCO below the temperature (T_Ag) of silver melting, wherein the temperature (T1) is between a minimum temperature (T_J) docking ReBCO and temperature (T_Ag) of silver melting (TJ<T1<T_Ag); annealing of resultant butt at second temperature (T2), which is lower than temperature (T_R) of transition of orthorhombic ReBCO to tetragonal phase (T2<T_R), during time (t) in medium, where partial pressure of oxygen is sufficient for repeated saturation with oxygen ReBCO at second temperature (T2).

EFFECT: possibility of high current density.
