Property optimization of BST-based composite glass ceramics for energy-storage applications
Source abstract
Abstract
Abstract A series of Ba 0.4 Sr 0.6 TiO 3 (BST)-based glass ceramics with different content of BST additive was prepared via sintering and crystallization route, and the subsequent phase evolution, microstructure and dielectric properties were investigated. Results showed that the BST additive obviously improved the dielectric constant of the BST-based glass ceramics. In addition, BST additive can modify the microstructure and reduce the activation energy of grain boundary, which led to an improvement in the dielectric breakdown strengths. The estimated energy density of BST-based glass ceramics with optimized composition reached up to 2.81 J/cm 3 , which was improved by 8.5 times as compared with that of the pure glass ceramics (0.33 J/cm 3 ).
