  1. 387. Effect of sheath material and reaction overpressure on Ag extrusions into the TiO2 insulation coating of Bi-2212 round wire

    Poster Presentation

    To develop a high winding current density in Bi2Sr2CaCu2Ox (Bi-2212) wires, it is important to use an insulating layer that is thin and fulfills the dielectric requirements. Ideally we would like to use a thin ceramic layer because the other option, braided glass fiber insulation, is about 5 to 10 times thicker and it reacts with the Ag sheath. To date, TiO2 seems to be the most viable ceramic...

  2. 178. Filament Damage in Bi2Sr2CaCu2O8-x (Bi-2212) Superconducting Wires as Revealed by External Etching

    Poster Presentation

    Recent increases in the critical current density of Bi2Sr2CaCu2O8-x (Bi-2212) composite wires have driven interest in superconducting magnet applications for this material. However, the round-wire composite material is comprised of brittle filaments in a soft silver matrix, leaving the wire susceptible to filament damage during operation.In this study, Bi-2212 wires were tested on a Walter...

  3. 130. Microstructure and superconducting properties of Bi,Pb-2223 thin films fabricated from alternately layered Bi,Pb-2212/Pb-Ca-Cu-O thin films

    Poster Presentation

    The microstructures and superconducting properties of the (Bi,Pb)2Sr2Ca2Cu3Ox superconductor (following, Bi,Pb–2223) fabricated by a multilayered precursor and a post-annealing process have been investigated in order to obtain high performance Bi-2223 wires and tapes using two kinds of sputtering targets of nominal compositions of Bi,Pb-2212 and CaCuPbO. We fabricated a alternately layered...

  4. 504. Strong, high Je Bi2212 round wire
    Dr Alexander Otto (Solid Material Solutions, LLC)
    11/07/2017, 13:00
    Poster Presentation

    A Bi2212-based, high temperature superconductor has been developed in reinforced, rectangular wire forms, with up to 400 MPa stress tolerances and useful current densities, making them suitable for application in some coils that are problematic with wide HTS tapes, and that need to operate beyond the field and temperature limits of low temperature superconductors. However, the development of a...
