In order to identify the superconducting phase in the Bi-Ca-Sr-Cu-O system, phase search experiments were performed. The results of power X-ray study, EPMA study, specific gravity measurements and oxygen analysis revealed that the compound having the composition Bi₂(Ca, Sr)₃Cu₂O₉ or Bi₂(Ca, Sr)_3-ΔxCu₂O_9-Δy is responsible for the high-T_c superconductivity. Two possible structure models, which are closely related to the structure of the bismuth titanate Bi₄Ti₃O₁₂, are proposed for this compound.
