Superconducting properties, phase chemical composition and crystal structure of Bi-Ca-Sr-Cu-O system sintered samples were investigated. Two-step resistive superconducting transitions with 120 K T/sub c/ onset were observed. The dominant phase composition might be formulated as Bi/sub 2/CaSr/sub 2/Cu/sub 2 + x/O/sub y/ where x = 0.4 - 1.0 depends upon heat treatment procedure.
