摘要：
The studies have been focused to the determination of the best elaboration conditions of Tl-1223 phases. The objectives were to obtain a well defined composition and an optimization of the superconducting behaviour by Tl/Pb, Sr/Ba and O/F substitutions. To reach these objectives, we have investigated the monophased field of Tl/Pb, Sr/Ba-1223 phase in dependence on composition and temperature and the compositional effect on the superconducting behaviour. Samples were elaborated by conventional solid state reaction in flowing oxygen from a stepwise process.
