Superconducting Bi2−xPbxSr2CaCu2Ox (noted Bi,Pb(2212)) has been processed in air at 860°C with a nominal composition of Bi1.72Pb0.34Sr1.83Ca0.97Cu2.13Ox in contrast to the literature where this phase was produced in argon around 740°C. With the aim of transforming this phase into Bi,Pb(2223) (another Bi-containing superconductor), Bi,Pb(2212) has also been mixed with Ca2CuO3 and CuO. A critical temperature Tc of 95K was obtained for pure Bi,Pb(2212). On the basis of DTA/TG and X-ray diffraction measurements, we can conclude that pure Bi,Pb(2212) melts at 882°C. If secondary phases are added, Pb leaves the Bi,Pb(2212) crystal structure around 400°C and it is again incorporated above 835°C until the phase melts at 876°C, a temperature somewhat lower due to compositional effects.
