This work investigated the electrical properties of BCZT-1.0 mol% BCZT-seeds ceramic systems doped with x mol% MnO₂. The BCZT seed was synthesized via molten-salt method. Then, the MnO₂ and 1.0 mol% BCZT were mixed with the starting materials of Ba_0.85Ca_0.15Ti_0.9Zr_0.1O₃ ceramics and prepared by mixed oxide method. The effect of MnO₂ on electrical properties of BCZT-BCZT seed ceramic was investigated. Results were found that the ceramics showed perovskite phase and no secondary phase for all samples. Density and grain size values were in the range of 5.45-5.57 g/cm³ and 6.79-9.85 μm, respectively. The highest values of ε_r and P_r measured at room temperatures were 3900 and 8.22 μC/cm², respectively which obtained at the sample of 1.0 mol% MnO₂. Tan δ of ceramic samples were lower than 0.02. In addition, d₃₃ and g₃₃ values were changed with MnO₂ content.
