- Abstract
In this paper, thick film antiferroelectric ceramics (1 − x)(Pb0.94La0.02Sm0.02)(Zr0.675Sn0.285Ti0.04)O3–xSrTiO3 [(1 − x)PSLZST–xSrTiO3, x = 0, 0.05, 0.1, 0.15, 0.2, 0.3, 0.4] were prepared by solid-phase sintering and tape-casting method. The effect of SrTiO3 additive on the microstructure, dielectric properties, and energy storage properties of PSLZST ceramics were investigated. The stable phase of the pure PSLZST ceramics is orthogonal perovskite phase. However, the stable phase is tetragonal perovskite phase when x = 0.05. The ceramics with x ≥ 0.1 are cubic perovskite structures. The grain distribution of PSLZST–SrTiO3 ceramics becomes more uniform with increased SrTiO3 concentration. The P–E curves of the (1 − x)PSLZST–xSrTiO3 ceramics gradually change from typical antiferroelectric curves to relaxor ferroelectric ones. Doping SrTiO3 is an effective means to improve the energy storage efficiency of the PSLZST antiferroelectric ceramics. The energy storage efficiency is 74% in the undoped PSLZST samples, while almost all the energy storage efficiencies of the PSLZST ceramic samples with SrTiO3 modified are greater than 80%. The maximum energy storage efficiency can reach 94.6% when x = 0.4. This indicates that the (1 − x)PSLZST–xSrTiO3 ceramics could be suitable for the applications of pulse power technology.
