Description
Doping of Bi-Pb-Sr-Ca-Cu-O HTSc's with Sb have been attempted with the purpose of increasing the transition temperature. In this paper, several different preparation methods were investigated in which the composition and annealing conditions were varied; ρ vs T and η vs T measurements were carried out to determine the superconducting properties of samples. X-rays, differential thermal analysis (DTA) and thermo gravimetric analysis (TG) were performed to study the structure and the melting behavior of samples. However, it was found that, at least for the conditions tested, Sb has no effect in increasing the transition temperature of this system. The maximum superconducting transition temperature observed in the system Bi2-xPbxSr2Ca2Cu3Oy was Tc,o = 108 K which was completely independent of the doping with Sb
