Lead-free piezoelectric 0.94(K0.5Na0.5)NbO3–0.06LiNbO3 (0.94KNN–0.06LN) ceramics were prepared by solid state reaction process modified by introducing polyvinylpyrrolidone (PVP) of different molecular weights in the starting raw materials. The chemical interaction between the metal cations and the P...
