Research Abstract

The Bi-2223superconducting tapes with seven filaments were fabricated to construct the superconducting cable conductor with 300 mm in length. The sizes of the cross section of the tapes are 2mm in width and 0.2mm in thickness, and the length of the tapes is 500mm. The sample fabricated by the first sintering condition of 850℃and 50h in air and the second sintering condition of 836℃and 100h in air showed the best critical current(I_C) property. The maximum I_C value was 3.8A for the tape with 500mm in length and 6.1A for the tape with 50mm in length.
