Abstract
xBa0.7Sr0.3TiO3-SrTiO3 (BST-ST) multilayer ceramics with different BST layers (x=1, 3, 5) were designed and fabricated by lamination of Ba0.7Sr0.3TiO3 (BST) and SrTiO3 (ST) tapes. Dielectric and energy storage properties of the multilayer ceramics were investigated. BST-ST multilayer ceramics exhibited enhanced temperature- and frequency-stability of dielectric properties, accompanying high permittivity (~2000) and low dielectric loss (<0.005) at room temperature. P-E loops revealed that BST-ST multilayer ceramics displayed low remnant polarization and favorable maximum polarization. The optimal energy storage performance was obtained in the composition of x=5 with dielectric breakdown strength of 220Â kV/cm and energy storage density of 2.3Â J/cm3. These results indicate that BST-ST multilayer ceramics can be a favorable candidate for dielectric capacitor applications.
