| Abstract: | A noval 0.95K0.47Na0.47Li0.06NbO3-0.05Ba（Zr1-xTix）O3 piezoelectric ceramic was prepared by traditional ceramic sintering technique. Its piezoelectric properties and microstructure were also studied. The results indicate that this new type ceramic sintered at 1 120℃ for 4 hours has not only a pure perovskite phase with tetragonal symmetry but also a pre - pressing ceramic body, and when x is 0.95, each property shows the best, as d 33 is 133 pC/N, k p is 34%, ε r is 1 138, Q m is 148, and tanδ is 0. 017. |
