Abstract
We report an elegant method for the synthesis of single-phase Bi-2223 superconductor from a stoichiometric composition Bi1.7Pb0.3Ca2Sr2Cu3Oy by a matrix reaction route. The superconducting transition temperatureT c (R=0) of this single-phase compound is 120 K. The effect of Pb-content and sintering temperature on the formation and stability of Bi-2223 phase is described.
