DEPENDENCE OF THE CRITICAL TEMPERATURE ON THE SYNTHESIS PARAMETERS OF Bi1.7Pb0.3Sr2CanCun-1Oy CUPRATES.

This article describes the preparation of BSCCO cuprate based on bismuth, the most common representative of high-temperature superconductors, and what should be paid attention to when preparing it. The advantages and disadvantages of obtaining BSCCO cuprate by the solid-phase reaction method are presented. At the same time, it was pointed out why the phase of the transition of this type of cuprates to superconductivity manifests itself in several phases, and not in one, and these reasons can be explained simply. BSCCO has several cuprate extraction technologies. The article sequentially presents the stages of obtaining by the method of solid-phase reaction.
