“…Table 1. It showed that the mechanical properties of the compounds were found to be linearly increased with the increasing of doping in Bi-2223 superconductors [12][13][14][15]. A sudden dropped was observed when x = 0.08 and this behaviour is might be due to the contribution of weak grain boundaries in the sample.…”

Bi-2223 superconductors doped with Fe 2 O 3 at Cu-site were prepared in bulk form using high purity oxide powders via solid state reaction technique with intermediate grinding. The series of Fe stoichiometric ratio (x = 0.00, 0.02, 0.04, 0.06, 0.08 and 0.10) are systematically added to Bi 1.6 Pb 0.4 Sr 2 Ca 2 Cu 3-x Fe x O y system to study the effect of Fe doping on mechanical and superconducting system properties. Vickers hardness, electrical resistivity, X-ray diffraction and Field Emission Scanning Electron Microscopy have been carried out to assess the effects of Fe doping. These measurements indicate that the Fe doping decreased the critical temperature and deteriorated formation of high T c phase, compared to undoped sample. Grain size of the samples were also reduced by increasing the amount of Fe and the mechanical properties were found to be escalate with the increasing of Fe concentration.

“…The effect of the partial substitution of Ca with Sm in Bi-2223 superconducting samples (Bi 1.6 Pb 0.4 Sr 2 Ca 2-x Sm x Cu 3 O y ), prepared using the conventional solid state reaction method, have been investigated by Yilmazlar and colleagues who used XRD, EDXRF, magneto-resistivity, critical temperature, transport critical current density and ac susceptibility measurements. 301 3.2.6 Thin films. As always, the section concerning the analysis of thin films is split between those applications that have prepared a material and have then undertaken characterization studies and those that have performed depth-profiling/diffusion studies.…”

“…, Mn [2], Sm [3] [4], Pr [5], Eu [6] and Gd [7] [8] Eu ions leads to a lowering of the formal Cu valence [3,4,6,7,8], while the replacement of Mn in a Ca site raises the Cu valence [2]. The result the Tc thus rises with increasing Mn [10], Zn [12] and Sn [1] on superconducting properties of Bi-Pb-Sr-Ca-Cu-O compound at Cu +3 sites.…”

By using a conventional solid-state reaction technique, a group of the superconducting samples with nominal composition Bi2-xPb0.3WxSr2Ca2Cu3O10±δ with (0≤x≤0.5) sintered at 840ᵒC for 140h in the air have been prepared. The effect substitution of tungsten nanoparticles on the physical properties of Bi sites was studied. X-ray diffraction (XRD) studies showed that all our samples are polycrystalline with orthorhombic structures and presence two phases: high-Tc phase (2223), low-Tc phase (2212) and an impurity phase Some impurities likeSr2Ca2Cu7Oδ, CaO and WO . In the prepared samples the lattice parameter values and the volume fraction of high-Tc phase are calculated. Electrical resistivity measurements show that the values of critical temperature Tc increase with tungsten content. The highest transition temperature, Tc, obtained for Bi2-xPb0.3WXSr2Ca2Cu3O10+δ composition was 191.8K with x=0.3.
