摘要：
High dense Ba0.5Sr0.5TiO3 ceramics with Al2O3 additives have been prepared by a method combined the sol–gel process and the solid state reaction. Phase compositions, microstructure and dielectric behaviors are investigated systematically. Our experiment results reveal that the Al2O3 additives reduce the dielectric constant slightly and increase the breakdown strength greatly due to the refined microstructure and the formation of the second phases. The estimated energy density of Ba0.5Sr0.5TiO3 ceramics with optimized Al2O3 additives is improved by 1.5 times as compared with that of pure Ba0.5Sr0.5TiO3 ceramics.
