On the synthesis and structure of single-phase (Bi, Pb)2Ca2Sr2Cu3O10
P V P S S Sastry J V Yakhmi R M Iyer
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 temperature
T 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. -

This paper describes the synthesis and microwave absorption studies of single phase Tl-2223 compound, with
T c=(129 ± 1) K. The single phase compound has been synthesized using a precursor matrix method. It has been found that Tl-deficient starting composition gives the best results.
