| Abstract: | 0.97(Na0.55K0.45)NbO3-0.03LiSbO3(97KNN-3LS) lead-free piezoelectric ceramics, the composition of which is deviation from the coexistence of the orthorhombic and tetragonal phases of (Na0.55K0.45)1-xLixNb1-xSbxO3 system, have been prepared by the conventional mixed oxide method. The microstructure and electrical properties of 97KNN-3LS ceramics were investigated with the influence of sintering temperature. The results of present work indicate that 97KNN-3LS ceramics with the optimum sintering temperature pos... |
