Superconductor YBa2-xAgxCu3O7- δ in a bulk form has been developed through modified sol-gel processing. The preparation involved dissolving metal organic precursor in a mixture of propanoic acid and propylamine which then undergo for annealing at 900 °C for 5 hours and sintering at 950 °C for 5 hours. The bulk samples were characterized using X-ray diffractogram (XRD), resistivity measurement technique and Scanning Electron Microscope (SEM). The highest TC value was found at 84 K for x=0.05. The value decrease as the Ag concentration increase. The highest JC value measured for x =0.05 were 5.977 A/cm2 at 50 K and 4.748 A/cm2 a 60 K. 123 phase remains as orthorhombic for all samples. SEM micrograph showed the clear grains for the pure samples and it became not visible as the Ag concentration increase.
