Özet

In this paper, the measured magnetic properties of Bi2Sr2CaCu2O (x) /3 wt.% Ag textured composite materials prepared by a LFZ melting technique at different growth speeds (5, 15, 30, and 60 mm/h) are presented. X-ray diffraction patterns have shown that Bi-2212 phase is the major one in all cases. The magnetization measurements have been carried out as a function of the magnetic field up to 10 kOe. J (c) values, calculated using Bean's model, indicate that the growth speeds have a significant effect on J (c) . It has been found that the maximum critical current density, 4.42x10(5) A/cm(2) at 10 K, has been obtained for the 15 mm/h grown sample.
