Comparative properties of Sr x Ba1−x TiO3 ferroelectric glass–ceramics prepared by powder sintering and melt casting



A series of strontium barium titanate ferroelectric glass–ceramics were prepared by both powder sintering and melt casting. The effects of composition and preparation method on the structure, phase development, dielectric behavior, breakdown strength and energy storage properties were investigated. For the glass–ceramic prepared by powder sintering, there is an increase in dielectric breakdown strength as well as energy storage density with the increasing Sr content. The average breakdown strength and energy storage density of the BST glass–ceramic prepared by melt casting were improved remarkably as compared with those of the sample prepared by powder sintering. The sample with Ba/Sr ratio of 40/60 prepared by melt casting showed an average breakdown strength of 588 kV/cm and an energy storage density of 2.08 J/cm3.
