Özet

Glass samples with a nominal composition of Bi1.2Ga0.4Pb0.4Sr2Ca2Cu3O10+y were prepared as rods having a diameter of 13 mm and 20 cm long by melt casting technique. Sintering process was performed by applying a direct current to the glass rods. Three different current application stages were used and crystallization of the glass rods were obtained. The XRD studies of the material showed that crystallized grains were preferably c-axis oriented. The best Tc was obtained at 107 K and Tzero was obtained at 101 K. These results were also confirmed by the D.C. Susceptibility measurements. After the optimum processing condition the maximum transport current density was found to be 9700 A/cm2 at 4.2 K.
