212-Vanadate ceramics with formula Bi2SrV2-xUxO9, where (0 ≤ x ≤ 0.6 mole ) were carefully synthesized by solution routes with sintering temperature at 880oC for 24 hrs. Structural analysis with XRD proved that uranium (IV)-dopant can substitute successfully until x = 0.55 mole on the Bi-layered perovskite crystal structure without damaging the original structure . It was observed that U – doping have slight to moderate effects on both ESR-signals and conduction mechanism of U-doped Bi-Sr-V-O regime. Electrical measurements indicated that the energy gap Eg and number of electrons in conduction band Ncb increase as the ratio of U doping increases from x = 0.05 till x = 0.6 mole respectively due to the increasing of paramagnetic character of uranium than vanadium.
