Pb,Sb 첨가에 의한 Bi-Sr-Ca-Cu-O게 초전도체 특성

Superconducting properties of Bi-Sr-Ca-Cu-O Superconductor doped Pb and Sb

Bi-Sr-Ca-Cu-O superconducting system has both the low and high Tc phases. We added Pb and sintered for 200hrs. in OS12T atmosphere in order to get the superconductor above critical temperature 100K. Superconducting properties of the Bi(Pb)SrCaCuO system doped Sb were also investigated. When Sb of 0.1mol is added, the sintering time becomes shorter than that doped Pb only. We could get the critical temperature 102K at the samples sintered for 24hrs. and 109K for 210hrs.
