Abstract :
Formation of bismuth-based high-Tc superconducting ceramics 2212 and 2223 with partial replacement of Bi by p-elements of group III (Ga, In), IV (Ge, Sn, Pb) or V (Sb) was studied. XRPD, DTA/TG, SEM/EDX, SQUID, and VSM were used for phase identification, structural analysis, grain morphology studies, chemical analysis and magnetic measurements.
