“…Glass which acts as liquid sintering aids may also plays an important role in achieving high energy density which has been recognized by many authors and our previous research [11,12]. In order to obtain a high energy storage density, BaTiO 3 and glasses have been employed to improve the dielectric breakdown strength (BDS) [13,14].…”

A series of (1 -x)(Na 0.5 Bi 0.5 )TiO 3 -xBaTiO 3 (abbreviated as NBT-xBT) (x = 0, 0.01, 0.05, 0.1, 0.15) ceramics with 3 mol% BaO-B 2 O 3 -SiO 2 glass additives were prepared via the solid state reaction route. Effect of the BaTiO 3 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 BaTiO 3 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% BaTiO 3 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°C.
