Substituted Bi-2212 and Bi-2223 HTSC

摘要

Formation of bismuth-based high-T_c superconducting ceramics 2212 and 2223 with partial replacement of Bi by p-(-elements of group Ⅲ (Ga, In, T1), 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.
