摘要：

We report an efficient and highly reproducible method for the preparation of the almost monophasic Tl-1223 phase by partial substitution of Ba2+ into Sr2+ sites in the stoichiometric compositions of (Tl0.6Pb0.2Bi0.2) (Sr2-xBax)Ca2Cu3O9 (x= 0.2-0.3). The as-synthesized samples have a superconducting transition temperature around 115 K which can be further increased up to 122 K after post-annealing at 820-degrees-C for 20 h in oxygen.
