Abstract

Lead-free piezoelectric ceramics (Na0.475K0.475Li0.05)(Nb0.92Ta0.05Sb0.03)O3added with different amounts of CeO2have been prepared by a conventional mixed-oxide method. After the addition of CeO2, the sintering performance of the ceramics is greatly improved. The ceramics can be well-sintered at a higher temperature, and hence have a higher density and better piezoelectric and dielectric properties. For the ceramic added with 0.4 wt% CeO2, the piezoelectric and dielectric properties become optimum, giving d33= 246 pC/N, kp= 0.50, εr= 1300 and tanδ= 4%.
