dc.description.abstract(0.99-x)(K0.5Na0.5)(Nb0.965Sb0.035)O3-0.01SrZrO3-x(Bi0.5Na0.5)ZrO3 ceramics are chosen as an example to illustrate the effects of phase boundaries on strain. Temperature-dependent dielectric permittivity and convergent beam electron diffraction patterns confirm the multiphase coexistence of rhombohedral, orthorhombic, and tetragonal phases in the ceramics with x = 0.03–0.04. Intriguingly, the ceramics with x = 0.03 display improved temperature stability in strain, e.g., a high retention (≈95%) of unipolar strain at 180 °C and low variation of 24% at 20–180 °C. A mode is proposed to show how to effectively tailor the strain and consolidate its temperature stability in potassium sodium niobate-based ceramics.
