Preparationand Study of the Structural Properties of Yttrium Barium Copper Oxide by X-ray Diffraction

Abstract

The aim of this study is to prepare three samples of the yttriumbariumcopper oxide (YBCO)compound, which is classified as a superconducting materialwith percentages of 100%, 90%, and 80%of the yttrium oxide in the compound respectively, in order to determine the effect ofincreasing or decreasing the percentage of yttrium oxide on the superconductiveproperty. The samples were prepared by the usual chemical method and then the three samples were tested using X-ray diffraction (XRD). The results showed that the samples prepared in their initial ratio are consistent with the compound with superconductivity characteristic with some difference in the values and shape of the primitive unit cell for each sample, the study concluded that the X - ray diffraction test confirms that the compound has superconductive properties, but further application tests such as Levitation and the Joseph Son junction are needed to estimate the Accurate value of the critical temperature of the compound.
