Despite early recognition that a relatively low-temperature superconductor occurs in samples of approximate composition Bi2Sr 2CuO6, studies of this material have been plagued by difficulties in the preparation of single phase material with a large superconducting fraction. We report the first preparation of ceramic samples in the Bi-Sr-Cu-O system that show bulk superconductivity at 4-15 K. Structural, chemical, and electronic characterizations of superconducting and nonsuperconducting ceramics of composition Bi2.05Sr 1.95CuO6 are described.
