Fabrication of YBa2Cu3O7−x Superconducting Wires by Spray Deposition

  • J. G. Wang

YBa2Cu3O7−x superconducting wires have been fabricated by spray deposition/pyrolysis of metal nitrate solutions using commercial carbon fibers as the substrate, followed by heating in air and annealing in O2. The Tc of the wires have been found to be 82 K and the Jc to be 2150 A/cm2 in zero field at 77 K. The heating/pyrolysis process was further studied by TGA and SEM. SEM pictures showed that the superconducting phase formed by slow heating/annealing was well-aligned and well-connected along the axial direction of the wires.
