Abstract
Semi-conductive BaO–B2O3–SiO2–Na2CO3–K2CO3 glass additives were added to Ba0.4Sr0.6TiO3 (BST) ceramics to investigate its influences on the microstructure, dielectric properties, breakdown strength (BDS), and energy storage density. The sintering temperatures were lowered about 150°C with a high relative density (∼98%). X-ray diffraction patterns of all BST glass ceramics suggest perovskite structures without any detectable secondary phase. Room temperature dielectric constant of BST glass ceramics decreases with increasing Na2CO3 content. BDS and energy storage density of BST glass ceramics increase with increasing Na2CO3 content, and reach their maxima of 280kV/cm and 0.72J/cm3 at the highest Na+ and K+ content. These results suggest that the BST glass ceramics could find their potential applications in energy storage capacitor devices.
