High energy storage efficiency and high electrostrictive coefficients in BNT–BS–xBT ferroelectric ceramics
TLDR
In this paper, the structure, morphology, ferroelectricity, strain, energy storage, dielectricity, and impedance of the BNT-BS-xBT ceramics are investigated.Abstract:
(1 − x)[0.9(Bi0.5Na0.5)TiO3–0.1BiScO3]–xBaTiO3 (BNT–BS–xBT) ceramics are prepared by the traditional solid-state sintering. The structure, morphology, ferroelectricity, strain, energy storage, dielectricity, and impedance of the BNT–BS–xBT ceramics are investigated. XRD shows that all ceramics have pseudo-cubic structures. The results also show that BT can refine the grain size of the ceramics and reduce the corresponding density. At x = 0.20, the energy storage performance of the ceramics is optimum (Wrec = 0.563 J/cm3, η = 63%). At x = 0.10, the electrostriction coefficient (Q33) of the ceramics reaches 2.72325 × 10−2 m4/C2. Dielectric and impedance spectroscopies show that the ceramics are relaxor ferroelectrics and have good insulation properties.read more
