Abstract
The microstructure and superconducting properties of Bi-2223/Ag tapes fabricated in high magnetic fields were investigated. The results show that the partialmelting temperature has influence on the formation of Bi-2223 phase and the Jc. The optimum partial-melting temperature is 855°C. The magnetic field during sintering at 830°C has no influence on the formation of Bi-2223 phase and the Jc. However, the magnetic field during partial-melting process has obvious influence on the formation of Bi-2223 phase and the Jc. The tape partially melted with 10 T magnetic field shows stronger c-axis alignment of Bi-2223 phase and higher Jcvalue than that partially melted without magnetic field.
