Ferroelectric dense cceramic compositions of (1-x)((Bi1/2Na1/2)0.94Ba0.06TiO3)-xBa1/2Sr1/2TiO3 (BNBT-BST), (0 ≤ x ≤ 0.1) were fabricated via sol-gel method. The phase, microstructural, dielectric, ferroelectric and temperature dependent properties were investigated in detail. The XRD revealed single phase perovskite structured Bi1/2Na1/2TiO3. The temperature dependent dielectric properties revealed two phase transitions in the fabricated samples. The Energy storage properties were obtained indirectly from the Polarization versus Electric field (P-E) loops at various temperature and electric field. The maximum values of the energy storage density (W) and energy storage efficiency (η) of 0.57 J cm-3 and 43% were obtained at 150 °C and 70 KV cm-1 for x = 0.08 respectively. The energy storage densities were observed to increase with increase in temperature and electric field. The optimum composition of BNBT-BST can be a promising candidate for energy storage applications.
