Özet
Glass-ceramic BSCCO superconductors with nominal (Bi2-delta-gammaGadeltaTlgamma)Sr2Ca2Cu3O10+x compositions, where delta=0.20, 0.40, 0.60 and gamma=0.10, 0.30, 0.40, have been prepared by the melt quenching method. The thermal conductivity, kappa(T) measurements were performed between 30K and 285K and results obtained found to be between 3.1 and 9.9 mW/cm.K depending an the substitution levels and temperature. Results obtained showed that the phonon-defect scattering dominates above the T-c for all samples but below the T-c a strong coupling mechanism occurs. The best electrical performance was obtained to be 113K and 107K for T-c and T-zero, respectively.
