Open AccessOptimized strain performance in <001>-textured Bi0.5Na0.5TiO3-based ceramics with ergodic relaxor state and core—shell microstructure
Herein, a high strain of ∼0.3% with a small hysteresis of 43% is achieved at a low electric field of 4 kV/mm in the highly <001>-textured 0.97(0.76Bi0.5Na0.5TiO3−0.24SrTiO3)−0.03NaNbO3 (BNT−ST−0.03NN) ceramics wi...

High energy storage, structure evolution and dielectric properties of complex perovskite solid solution (1-x) NaNbO3-xBi (Zn2/3Nb1/3) O3
NaNbO3-based lead-free ceramics show great potential in energy storage and piezoelectric applications due to the antiferroelectric and ferroelectric features. However, pure NaNbO3 usually shows lossy hysteresis l...
