| Abstract | ||
| A ceramic superconductor compounds with the composition (YBa2Cu3O6.85)0.8Ag0.2 are prepared by solid state reaction from the principle routs like Y2O3,BaCO3 and Ag2O with high purity 99.99%. Different measurement were made to show the improvement in high phase superconductor such as resistivity measurement , X-ray diffraction(XRD) and scanning electron microscope (SEM). Resistivity measurement consider good tool for determination the critical temperature (Tc) . A better (Tc) value appeared at( x=0.2) , that is related to the amount of (Ag ) in the mixture , and nearly equal to (124K) comparable with the pure compound which does not normally exhibited Tc-value greater than (100K) in a YBCO-compound. X-ray exhibited to orthorhombic phase related to high Tc phase .SEM pictures emphasized the presence of high phase through the surface morphology for the samples under study. | ||
