عنوان المقالة: The Influence of Partial Substation of Antimony & Lanthanum Oxides on Electrical and Structural Properties for the Superconductor Compound Bi2- xSbxBa2Ca2-yLayCu3O10+
In this research the Bi2-xSbxBa2Ca2-yLayCu3O10+compound was prepared and studied the
influence of partial substation of Sb2O3 and La2O3 on the electrical and structural properties Samples
synthesis by solid state reaction method .The examination of XRD diffraction shown that all samples have
bulk polycrystalline with orthorhombic structure. The results shows that the increasing of the c-axis lattice
constant for the samples substation with Sb2O3 and La2O3 as compared with those have no content, It was
found that changing in lattice parameters (a,b), ratio c/a ,mass density and volume fraction Vphases with
increases of (Sb2O3,La2O3) concentration. All samples have highest phase 2223 major relative to the other
phases. The electrical properties tested by using four probes technique to calculation critical temperatures,
it was found the sample Bi1.6Sb0.4Ba2Ca1.8La0.2Cu3O10+ has a highest critical temperatures Tc=122.5K.
