| Abstract: | Transition metal oxides, also can be used as a dopant in the not only can be used as a sintering aid, to improve ceramics sintering characteristics, but ceramic to substitute ions to improve the performance ceramics. This paper describes the impact on sintering characteristics, microstructure, dielectric, piezoelectric and ferroelectric properties of KNN-based lead-free piezoelectric ceramics modified by transition metal oxides, the major role of the transition metal oxides in the modification of KNN-based lead-flee piezoelectric ceramics is analyzed and summarized to provide a reference for the future researches on the sintering aid modified KNN-based lead-free piezoelectric ceramics. |
