Özet

The Glass rods with nominal composition of (Bi2-alphaTlalpha)Sr(2)Ca(2)Cu3O(10+z) where alpha = 0.15, 0.25 and 0.35 have been prepared by melt casting technique. Preferably c-axis oriented grains were grown after the sintering process. The thermal conductivity kappa(T) measurements were performed between 30K and 290K and calculations were mad: using Wiedemann-Franz law. The kappa(T) values of the samples varied between 3.8 to 8.3 mW/cm.K and showed strong dependence to the heating temperatures and compositions. The best T-c and T-zero were obtained to be 122 K and 115 K respectively.
