摘要：
BaTiO3-Bi(Mg0.5Zr0.25Ti0.25)O3 ceramic was prepared by a solid-state method, and the influence of Bi(Mg0.5Zr0.25Ti0.25)O3 content on the microstructure, dielectric, ferroelectric and energy storage properties of BaTiO3-based ceramics was investigated. The ceramic has a tetragonal phase structure when the sample composition x≤0.03, and the structure of the ceramic changes from a tetragonal phase to a cubic phase when x≥0.06. This ceramic shows a good temperature stability. The dielectric constant peak becomes wider and lower, and the material gradually changes from a ferroelectric to a relaxor ferroelectric as Bi(Mg0.5Zr0.25Ti0.25)O3 content in the composition increases. The dielectric constant of the sample keeps stable from room temperature to 500 ℃. The addition of Bi(Mg0.5Zr0.25Ti0.25)O3 can make the hysteresis loop to be slimer, the remnant polarization Pr decreases, and the integral area of the upper branch of P–E loop with respect to the polarization axis become larger. Thus, the material energy storage density increases. The energy storage density of the material firstly increases and then decreases, while the energy storage efficiency increases from 75.08% to 92.35%. The maximum energy density of 0.80 J/cm3 can be obtained with a high efficiency of 88.97% as x=0.1. © 2023 Chinese Ceramic Society. All rights reserved.
