Potassium barium niobate-based glass ceramics doped with different proportion of Gd2O3 were fabricated by conventional melts and controllable crystallization. The influence of Gd2O3 content was further investigated on the phase compositional change, energy storage performance and charge-discharge properties of the optimized glass ceramics (crystallization temperature 900 degrees C). The microstructure has been remarkably transformed through the addition of Gd2O3. On the basis of the results, the doping of 1.0% Gd2O3 achieved a remarkable improvement on the energy storage density that reached 12.14 J/cm(3) with a dielectric breakdown strength (BDS) of 1818 kV/cm and dielectric constant of 83. The discharge efficiency of 80% and discharge time of 25 ns were obtained in the glass ceramics with 1.0% Gd2O3, which illustrated the excellent charge-discharge properties of Gd2O3-doped glass ceramics.
