Abstract
The results of the unleaded synthesis, and superconducting properties, and phase composition investigation of high-T/sub c/ superconductors obtained in the BiSrCaCuO (BSCCO system), when partially substituting copper oxide for copper are presented. Synthesized under special conditions, samples of BiSrCa((1-x)CuO+xCu))/sub 2/Oy with x=(0.2-0.3) revealed T/sub c/(R=0)=(102-107)K and consisted of the single superconducting phase Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub y/. The other impurity phases were not superconductors.
