The purpose of the current work was to evaluate the effect of Radiation of Gamma on the superconducting characteristics of the compound PbBr2Ca1.9Sb0.1Cu3O8+ δ utilizing a 137Cs source at doses of 10, 15, and 20MRad. Solid state reaction technology was used to prepare the samples. Before and after irradiation, X-ray diffraction (XRD) and superconductor properties were examined. Results indicated that the tetragonal structure of our chemical corresponds to the Pb-1223 phase with an increase in the ratio c/a as a result of gamma irradiation. (Tc (onset)) and on set temperature Tc (offset)) were also dropping from 113 to the 85.6 K and 129.5 to 97 K, respectively, for a transition temperatures.

“…Investigations were made and it was found that the system of Bi-Sr-Ca-Cu-O has a high degree of superconductivity at high temperatures. [7][8][9] X-ray diffraction analysis performed as part of the research showed that the two phases of Bi-2212 and (Bi,Pb)-2223 coexist in samples with rhombic crystal structures. The initiation critical temperatures (T c onset temperatures) and the critical temperatures for zero T c electrical resistance (R = 0) were determined from DC electrical resistance measurements by phase determination, and the microscopic properties of the samples were examined by SEM and XRD.…”

This study focuses on how the partial substitution of copper by nickel nanoparticles affects the electrical and structural properties of the Bi 2 Ba 2 Ca 2 Cu 2.9 Ni 0.1 O 10+δ , Bi 2 Ba 2 Ca 2 Cu 2.8 Ni 0.2 O 10+δ and Bi 2 Ba 2 Ca 2 Cu 2.6 Ni 0.4 O 10+δ compounds. Approximate values of crystallization size and crystallization percentage for the three compounds were calculated using the Scherer, modified Scherer, and Williamson-Hall methods. A great similarity was observed in the crystal size values from the Scherer method, 243.442 nm, and the Williamson-Hall method, 243.794 nm for the second sample. At the same time this sample exhibited the highest crystal size value for the three methods. In the examination of electrical properties, the sample with 0.1 partial substitution, Bi 2 Ba 2 Ca 2 Cu 2.9 Ni 0.1 O 10+δ was determined to be the best with a critical temperature of 100 K and an energy gap of 6.57639 × 10 -21 MeV. Using the SEM technique to analyze the structural morphology of the three phases, it was discovered that the size of the granular forms exceeds 25 nm. It was determined that the samples' shapes alter when nickel concentration rises. The patterns that reveal the distribution of the crystal structure also exhibit clear homogeneity.

In this paper, the compound Tl0.9Hg0.1Sr2Ca2Cu3O8+δ was produced using solid status reaction procedure. The crystal construction of specimen was studied using x-ray deviation device. X-ray diffraction (XRD) study of the crystalline nature confirmed that the sample of compound has a lattice structure from a mixture for different phases, it is has a tetragonal structure. The crystal size was calculated and investigated from the traditional Debye-Scherer method and the modified method for it. It is note the approximate values of crystal size and crystallinity in percentage between the modified Scherer method and the traditional Debye-Scherer method change depending on the peaks intensity of XRD diagram. Furthermore, the sample was taken into account to determine the physical and microstructure factors such as crystal strain.
