摘要：
A new lead-free ceramic system (1-x) (Bi0.5Na0.5Ti0.95Al0.025Nb0.025O3) -x(SrSc0.5Nb0.5O3) [(1-x) BNTA-xSSN, x=0.05、0.1、0.15、0.2] was prepared by solid-state method. The effects of the introduction of SrSc0.5Nb0.5O3 on the structure, phase transformation, energy storage and dielectric properties were studied. The results showed that (1-x)BNTA-xSSN owns perovskite structure at room temperature. The Tm decreases with the increase of SSN content, and the phase structure changes from tetragonal phase to pseudo-cubic phase. The ferroelectric properties of the ceramics were weakened and the relaxation ferroelectric properties were enhanced. When x=10%, the maximum effective energy storage density (Wrec) of BNTA-SSN ceramics is 2.7 J/cm3. The maximum energy storage efficiency (η) of BNTA-SSN ceramics is 85% at x=15%. © 2023 Chinese Journal of Materials Research. All rights reserved.
