Effect of fluorine doping on phase formation and properties of Bi(Pb)-2223 ceramics
(Elsevier Science Bv, 2011)
Superconducting ceramics of Bi1.6Pb0.4Sr2Ca2Cu3OyFx (x = 0-0.6) are prepared in air by conventional solid state reaction and characterized. The study shows that the melting point of the samples decreases as fluorine content ...
Structural and electrical properties of cerium doped Bi(Pb)-2212 phases
In this work, a comparative study on the effect of doping by low content cerium at Ca site of Bi(Pb)-2212 phases is presented. Superconducting ceramics of nominal compositions Bi2Sr2Ca1-xCexCu2O8+delta (called CC series) ...
