## Abstract The dielectric and the piezoelectric properties of the (1–__x__)(Na~0.5~K~0.5~)NbO~3~–__x__SrTiO~3~ ceramics, densified by the Spark‐Plasma‐Sintering method, have been studied. A phase diagram was established from the temperature dependence of the dielectric constant. A tetragonal–ortho
Potassium sodium niobate (KNN) piezoelectric ceramics and KNN substituted with lithium (Li + ) and antimony (Sb 5+ ) have been synthesized by the conventional solid state sintering method. This work focuses on the phase transition in the KNN system at potassium (K + ) content of approximately 0.35.
