Superconducting compounds of composition Y0.9 Pr0.1Ba2 [Cu1-yZny]3O7-δ (0 ≤ y ≤ 0.10) have been synthesized. The structure of these materials has been studied using powder X-ray diffraction technique and refinement has been carried out by using Rietveld refinement procedure. It has been shown that all these compounds crystallize in orthorhombic structure with slight change in c parameter. Increase of parameter O(2) and decrease of parameter O(3)suggest the changes in the Cu-O2 plane of these orthorhombic materials on Zn substitution.

In this research, we synthesized Y123 superconductor and Y235 superconductor doped with fluorine by solid sate reaction with Y2O3, BaCO3, CuO and CuF2 as precursor. The physical properties of Y235+Fx (Y2Ba3Cu5Oy-xFx) and Y123+Fx (YBa2Cu3Oy-xFx) superconductors were studied at x = 0,0.1, 0.2. The calcinations process was done twice in air at 810 °C for 24 hr and was increased to 925 °C for one hour. The sintering process was done at 925 °C for 24 hr and reduced to 500 °C for 24 hr. Our samples obtained were characterization by the four point probe technique, SEM and EDX, respectively. The surface of all samples were inhomogeneous and no impurity. The critical temperature onset of Y123+Fx and Y235+Fx were equal to 92 K, 95 K, 93 K and 92 K, 93 K, 92 K with x= 0, 0.1, 0.2, respectively.
