The authors have studied the electrical properties of polycrystalline pellets of the high-T{sub c} superconducting phases occurring in the Bi{sub 2}O{sub 3}-SrO-CaO-CuO (BSCCO) system, having nominal compositions Bi{sub 2}Sr{sub 2}Cu{sub 1}O{sub 6+y} (2201 phase, with T{sub c} = 10 K), Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+y} (2212 phase, with T{sub c} = 85 K), and Bi{sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10+y} (2223 phase, with {Tc} = 110 K). Pellets containing the 2223 phase having zero resistance below 105 K were obtained. For the 2212 and 2223 phases, the transport critical current density was measured as a function of temperature and of the externally applied magnetic field. As previously found for YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} (YBCO), results are consistent with the occurrence of a weak superconducting coupling among the grains. Such coupling was, however, noticeably stronger for the 2223 phase than for the 2212 phase.
