摘要：
A series of (1 - x)(Na0.5Bi0.5)TiO3-xBaTiO(3) (abbreviated as NBT-xBT) (x = 0, 0.01, 0.05, 0.1, 0.15) ceramics with 3 mol% BaO-B2O3-SiO2 glass additives were prepared via the solid state reaction route. Effect of the BaTiO3 content on microstructures, phase evolution, dielectric, and ferroelectric and energy storage properties of NBT-xBT glass ceramics has been investigated. X-ray diffraction studies of NBT-xBT ceramics with glass of 3 mol% were a perovskite structure without the secondary phase. With increasing BaTiO3 additive in the ceramics, the dielectric constant and the dielectric breakdown strength exhibited a gradual increase firstly and then slightly decrease. The addition of 5 mol% BaTiO3 to the ceramics improved the dielectric constant and energy storage properties remarkably, and the maximum recoverable discharged energy density of 0.68 J/cm(3) with an energy efficiency of 71 % was obtained by the sintering at 1035 degrees C.
