What is Superconducting and crystallographic properties of Bi,Pb(2212) about?
Superconducting Bi2.xPbxSr2CaCu20 x (noted Bi,F~2212)) has been processed in air at 860°C with a nominal composition of Bi 1.72pbo.34srl.83Cao.97Cl12.13Ox in contrast to the literature where this phase was produced in argon around 740°C. With the aim of transforming this phase into Bi,F~b(2223) (another Bi-containing superconductor), Bi,PI~2212) has also been mixed with Ca,2CuO 3 and CuO. A critical temperature T~ 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.
