Abstract
In this work, we reported on investigations of the effect of the simultaneous replacement of Sb in Bi-base superconductors by adding an amount of Sb on the Bi2-xSbx Ba2Ca2Cu3O10+ δ compound. The solid state reaction was applied under optimum conditions. Polycrystalline samples were prepared by solid state reaction. It has been observed that it has grown Bi2-xSbx Ba2Ca2Cu3O10+ δ (with x = 0.00, 0.05, 0.10, 0.15 and 0.2) corresponds to the 2223 phase. The x-ray data of the orthorhombic structure sample appears with a high ratio of the 2223 superconducting phase. The samples showed a transition temperatures Tc(onset) were 112 K, 115 K, 116 K, 119 and 121.6 K at (x = 0.00, 0.05, 0.10, 0.1.5 and 0.20) respectively, and the transition temperatures at zero resistance Tc(off) were 96, 103, 111, 114 and 117 K, respectively. X-ray diffraction analysis showed a change in the fixed lattice of the c-axis of the samples doped with Sb compared with these no Sb content. The change of Sb concentrations for all of our samples was found to result in a change in density ρm, C/a and volume fraction VPh(1223).
