摘      要：(0:74-x)(Na_(0.5)Bi_(0.5))TiO_(3)-xBaTiO_(3)-0.26SrTiO_(3)(x=0~0.1)(abbreviated as NBT-xBT-ST)lead-free ceramics were fabricated by a solid-state reaction *** effect of Ba doping amount x on the structure and energy storage properties of NBT-xBT-ST ceramics were *** the NBT-xBT-ST ceramics showed single perovskite structure with a pseudocubic *** doping effectively suppressed grain growth,in favor of forming small and uniform *** ceramics with a composition of x=0.04,an optimized energy storage density(γ=0.47 J/cm^(3))and efficiency(η=48:67%),under an applied electric field of 50 kV/cm,should be a candidate for solid-state compact pulsed power capacitor materials.
