“…So, the nanoparticles in this ratio seem to act as phase stabilizer for Bi-2223; as well as, the increase in lattice parameter (c) revealed that cations of the, Ca 2+ in addition to Bi 3+ may partly be substituted by Cd +2 and Sb +3 ions respectively, similar behavior was obtained by other authors for different compounds of superconductor materials [17,18]. While the shortened in lattice parameter (c) could be, attributed to the increment the amount of oxygen in BPbSCCO system, according to what mentioned in the literature [19].…”

High temperature superconductors materials with composition Bi1.6-xSbxPb0.4Sr2Ca2-yCdyCu3OZ (x = 0, 0.1, 0.2 and 0.3) and (y = 0.01 and 0.02), were prepared by using the chemical reaction in solid-state ways, and test influence of partial replacement of Bi and Ca with Sb and Cd respectively on the superconducting properties, all samples were sintered at the same temperature (850 oC) and for the same time (195 h). The structural analysis of the prepared samples was carried out using X-ray diffraction (XRD) measurements performed at room temperature, scanning electron microscope (SEM) and dc electrical resistivity was measured as a function of temperature. It was found that the sample prepared by partial substitution of Sb at ratio (x= 0.2) and Cd with ratio (y=0.01), has the maximum value of zero resistance temperature, where was the TC(onset) and TC(0) values for this sample are (140 K) and (123 K) respectively, and XRD results reveal that this sample has the highest percentage of Bi- 2223 phase, as well as the analysis of XRD patterns of the prepared materials showed polycrystalline structure and signalize that all samples had an orthorhombic crystalline structure. It was concluded that Sb2O3 nanoparticles it may be acts as a flux agent in the matrix to lower the partial melting temperature of the samples and that leads to the promotion of the high-TC phase.

“…% of Fe 3 O 4 nanoparticles were added to (Bi, Pb) 2 Sr 2 Ca 2 Cu 3 O 10 superconductors, and enhanced J c both in absence and presence of magnetic was reported [18]. Nano-sized Co 3 O 4 and MgO particles were added to Bi(Pb)-Sr-CaCu-O superconductors and improved superconducting properties were observed [19,20].…”

“…In the present work, we report the influence of partial substitution of Sr doping on the superconducting properties of the superconducting system Bi 2 Ba 2-y Sr y Ca 2 Cu 3 O 10+δ , with (y= 0 ,0.1 ,0.2 ,0.3 ,0.4) . Therefore, the volume fraction of the 2223 phase (Vph-2223) in our samples was determined by using the flowing equation [11]: The crystal lattice parameters (a, b and c) from a set of measured and indexed Bragg angles were calculated by using a computational program.The density of the prepared samples(ρ m ) were calculated by using the following equation [12]:…”

This study included preparing samples of the compound (Bi2Ba2Ca2Cu3O10+δ) by the solid state reaction method under a hydrostatic pressure 8 ton/cm2 and annealing temperature 840oC. X-ray diffraction (XRD), scanning electron microscopy (SEM), dc electrical resistivity measurements by four point probe method were used to investigate the microstructural and superconducting properties of Bi¬2223 samples. The X-rays diffraction study for the compound (Bi2Ba2Ca2Cu3O10+δ ) showed that it has Tetragonal type of crystal structure. The partial replacement of the component Ag in Bi, and Sr component in Ba simultaneously, the compound becomes (Bi2-xAgxBa2-ySryCa2Cu3O10+δ) with (x ,y) values equal to (x= 0.2, y= 0.1, 0.2, 0.3,0.4). The study of the crystal structure test showed that the structure retains on the tetragonal type with a high Tc phases (2223), low Tc phase(2212) and impurity phases, and the critical temperature Tc steps-up from (125K) to (137K) at substitution rate (x= 0.2, y= 0.1). But at increasing the substitution rate for (y) and the stability of (x) rate more than (x= 0.2, y= 0.1), the temperature declines to (108 K). Finally, the microstructural of the samples has been studies and tested by Scanning Electron Microscope for knowing the components' rates in the compound; how the compound partial substitution affect in the components; and specifying the quantitative and qualitative rates of the components in the compound.
