Superconducting Bi2.xPbxSr2CaCu20 x (noted Bi,F~2212)) has been processed in air at 860Β°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 740Β°C. With the aim of transforming this phase into Bi,F~b(2223) (ano
The effects of Y and Pb co-doping on phase evolution, microstructure, electrical and superconducting properties of Bi-2212 have been studied. The results show that Y 3+ ions enter into the crystal structure by replacing Ca 2+ and/or Sr 2+ ions, and hence reduce hole concentration in the electronic s
