✦ Synopsis

One of the ways to increase pinning force in superconductors is to create small precipitates of secondary phases in the bulk matrix. The samples of superconductor Bi, ,x Sr,_XCa,Cu,O, with different compositions have been decomposed

according to the phase diagram of the BiO , .5 -Sr&CaO-CuO system. The study showed that microstructure of samples and critical parameters were changed.
