From a consideration of the phase equilibrium diagram of the system Bi203-SrO-CaO-CuO, a simple annealing procedure was developed to precipitate Bi2+xSr2\_xCuO6+a, Sr14Ct124041\_ x and BieSr306 in high-temperature superconducting "Bi2Sr2CaCu208" ceramics. The transformation results in a four-fold in
