(K,Na)NbO3(KNN)-based lead-free piezoelectric ceramics is considered as one of the most promising alternatives for the state-of-the-art materials,lead zirconate titanate(PZT),which contains a large portion of hazardous lead substance.At the moment,the most effective approach for property enhancement of KNN-based ceramics is to form solid solutions with other species,such as LiNbO3,LiTaO3,etc,which is due to PPT effect,the abbreviation of polymorphism phase transition.
