Impedance-frequency spectrum and doping characteristics of lead-free K0.5Na0.5NbO3-LiSbO3-BiFeO3 ceramics

摘要：

　　Lead-free K0.5Na0.5NbO3-LiSbO3-BiFeO3 ceramics were prepared by traditional ceramic processing.The soft and hard doping characteristics of the ceramics were investigated by impedance-frequency spectrum method.Results show that the single BF-doping KNN ceramics show hard characteristics,and the BF-doping 0.95KNN-0.05LS ceramics shows soft characteristics.Whats more,the single LS-doping KNN ceramics show soft characteristics.And LS-doping KNN-BM ceramics also show soft characteristics.In a word,the LS and BF co-doping make KNN ceramics to show soft and hard doping characteristics at the same time.Because the soft doping of LS in KNN is more preponderant than that of BF,the co-doping KNN ceramics show soft doping characteristics as a whole.
