Açıklama
Pure and Nb2O5 added Bi1.6Pb0.4NbxSr2Ca2Cu3O delta superconductors (0 <= x <= 0.30) were synthesized by the ammonium nitrate melt route. Fraction of the high T-c 2223 phase increases with addition of small amounts of Nb. AC susceptibility and transport measurements showed the optimum Nb concentration as x = 0.10. Nb additions above x = 0.20 decrease significantly the fraction of the high-T-c phase and degrade the superconducting properties.
