Abstract

The microstructure and superconducting properties of Bi-based superconducting tapes fabricated in high magnetic fields were investigated. The flat tapes 0.6 mm in thickness and 3 mm in width set on the an isolite holder were sintered at 835-850 °C for 120 h in 0 or 10 T magnetic field in air. The results show that the tape sintered with 10 T magnetic field shows stronger c-axis alignment of the Bi-2223 phase and higher J_c value than that sintered without magnetic field. The tape sintered at 835 °C in a 10 T magnetic field shows a high proportion of Bi-2223 phase, however, a low c-axis alignment of the Bi-2223 phase. The tape sintered above 845 °C in a 10 T magnetic field shows a strong c-axis alignment of the Bi-2223 phase, however, a low proportion of Bi-2223 phase. The tape sintered at 840 °C in a 10 T magnetic field shows a strong c-axis alignment of the Bi-2223 phase, a high proportion of Bi-2223 phase, and the highest J_c value.
