Abstract

Lead-free (1-x)K0.49Na0.51NbO3-xLiNbO3 (KNN-LN, x = 0 ~ 0.08) piezoelectric ceramics were prepared by the conventional solid-state sintering method. The effects of LiNbO3 doping amount x on the phase transition behavior and the electrical properties of KNN-LN ceramics were investigated. By increasing LiNbO3 doping amount x, the orthorhombic-tetragonal polymorphic phase transition (PPT) temperature (T o–t) of KNN-LN ceramics shifted downwards, however, the Curie temperature (T c) slightly moved upwards. The room temperature phase structure thus changed from orthorhombic to tetragonal across the compositions with 0.05 ≤ x ≤ 0.06, named as PPT region. The composition with x = 0.06 in the tetragonal side of PPT region exhibited optimized electrical properties of d 33 = 246pC/N, k p = 41.6%, ε r = 679, tgδ = 0.028, and Q m = 52. In addition to its very high T c = 467 °C, this ceramic can be an excellent candidate for replacing the lead-based piezoceramics in high temperature applications.
