“…Based on such considerations, Sr-doping is adopted to stabilize the perovskite structure and increase dielectric relaxation behaviour [1,8]. In addition, Bi(Mg 1/2 Ti 1/2 )O 3 (BiMT) component is added to form a solid solution, promote sintering capability and in-hibit grain growth [6,9]. Bi 3+ with valence electron configuration of 6s 2 6p 0 can also increase polarization of the perovskite solid solution via hybridization with O 2p orbital, and disturb long-range ferroelectric order and increase relaxation characteristics as well via filling the A-site of the perovskite structure [10].…”

Perovskite (1-x)Ba0.9Sr0.1TiO3-xBi(Mg1/2Ti1/2)O3 (BST-BiMT-x) ceramics were prepared by sintering the corresponding powders synthesized by combining of solid state reaction method with citrate sol-gel and selfcombustion techniques. Submicron grains morphology, high density and large resistivity were obtained in the BST-BiMT-x ceramics. In addition, the BST-BiMT-0.1 and BST-BiMT-0.075 ceramics exhibit ferroelectric hysteresis loops with slim shape which lead to enhanced energy-storage properties. The energy-storage density of these two ceramics increases almost linearly with increasing the applied electric filed. The energy-storage density and efficiency at 25 kV/cm of the BST-BiMT-0.1 and BST-BiMT-0.075 ceramics sintered at 1200?C are 141.2mJ/cm3 and 79.3%, and 158.1mJ/cm3 and 76.7%, respectively, surpassing many recently reported values for ferroelectric/antiferroelectric ceramics. The enhanced energy-storage density and efficiency under low electric field can be attributed to the slim polarization-electric field hysteresis loops, high density accompanied by submicron grains morphology and pure perovskite structure.

We synthesized lead-free ([Formula: see text]CaZrO3–[Formula: see text]SrTiO3 solid-solution ceramics and studied their structure, dielectric and energy storage properties. X-ray diffraction and scanning electron microscope reveal the microstructure of the samples. A high temperature dielectric relaxation behavior at the temperature ranges of 200[Formula: see text]C–550[Formula: see text]C is found for [Formula: see text], 0.5 and 0.7 samples. We explore that the origin of high temperature dielectric relaxation behavior is related to the migration of oxygen vacancies by Arrhenius law and oxygen treatment experiment. Moreover, with the increase of SrTiO3 content, the 0.3CaZrO3–0.7SrTiO3 exhibits high dielectric constant ([Formula: see text] at 1 kHz), low dielectric loss ([Formula: see text] at 1 kHz), good energy density ([Formula: see text] J/cm[Formula: see text] and high efficiency ([Formula: see text]%) simultaneously, and the possible causes of energy storage behavior dependence are analyzed in detail.
