The method of joining of the BSCCO superconductors

To lengthen high-T/sub c/ superconducting wares (wires, screens and other) we present a method of joining of BSCCO materials, retaining their initial superconducting properties. The BSCCO original superconducting materials (tubes) were prepared by the melt quenching method with subsequent annealing. The initial superconducting temperature T/sub c//sup 0/ (R=0) of the BSCCO tubes is (85-92) K. For joining of the tubes the BSCCO superconducting material containing additions that decreased the synthesis regimes of BSCCO joining contact (splice) are used. The superconducting property and phase investigations of the original and joined BSCCO tubes are presented.
