Yakıncı] We have produced the (BiPb)2VxSr2Ca3Cu4−y TiyO12+δ with x=0.1 and y=0.050,0.10,0.2 and 0.3 compounds by melt-quenching method. Structural and superconducting properties of the produced samples were investigated by Scanning Electron Microscopy, X-ray diffraction patterns, electrical resistance measurements and dc-magnetic hysteresis loop measurements. The pure high-T c phase (2223) is nearly found with Ti substitution for x=0.05 and 0.10. The onset critical temperature (T c.onset) of the samples increases up to 111 K with doping up to x=0.20. In addition, considerable large values of the critical current densities (J c), calculated from the hysteresis loop measurements by using Bean's critical state model are obtained for the samples in the same doping range. Our data have indicated that J c decreases with increasing temperature and Ti concentration.
