Pure (K0.48Na0.52)NbO3 and (K0.48Na0.52)NbO3-2%mol KF (abbreviated as KNN and KNN-KF, respectively) ceramics were synthesized by means of solid-state sintering. Ferroelectric and dielectric properties of KNN and KNN-KF were investigated comparatively. Microscopic electrical performance of KNN-KF was...
