Abstract
This work concerns the results obtained during attempts of substitution of bismuth by antimony in superconductors Bi-cuprates family. The samples, prepared by dry way, from oxides and carbonates of the corresponding elements, are characterized by IR spectroscopy, X ray diffraction and differential thermal analysis. In every case, two domains appear:

- for antimony concentration lower than 50 %, the main phase is isotype with the yellow phase Bi₂Sr₃CaO₇.

- for a concentration between 50% and 100%, we systematically obtain a perovskite isotype with Sr_1.45Sb_0.55O $_{3\hbox{-}{\rm y}}$
