Abstract

The CaF₂–4LiF additive was added into SrTiO₃ ceramics in order to decrease the sintering temperature for compact pulse power application. The crystalline structure, microstructure and energy storage performance of sintered ceramics were studied. Incorporating CaF₂–4LiF additive to SrTiO₃ ceramics contributes to a notably enhancement of the energy storage density. The great enhancement in energy storage density occurred due to the notable increase in breakdown strength and the refinement of microstructure. With 2 at% additive, the samples exhibited an average breakdown strength of 31.8 kV/mm, and an energy storage density of 1.212 J/cm³ which is about 1.4 times higher than pure SrTiO₃.
