Abstract

In the present work, a series of (1-x)BaTiO₃-xBi(Li_1/3Hf_2/3)O₃ (0.08 ≤ × ≤ 0.14) ceramics were prepared via solid state reaction method. All the compositions were found to belong to a perovskite phase by X-ray diffraction. As x value increased from 0.08 to 0.12, the breakdown strength increased from 175 kV/cm to 240 kV/cm, resulting maximum values of both charge and discharge energy densities, ~ 1.71 J·cm⁻³ and ~ 1.65 J·cm⁻³ respectively, in the 0.88BaTiO₃-0.12Bi(Li_1/3Hf_2/3)O₃ ceramic with a high efficiency about ~ 95.6%. The low dielectric loss, high breakdown strength makes this system a good candidate for high power pulse devices applications.
