摘要Abstract: Lead-free, potassium sodium niobate piezoelectric ceramics substituted with lithium K0.5Na0.5NbO3 have been synthesized by traditional solid state sintering. The compositions chosen are among those recently reported to show high dielectric properties. We show that high densities and dielectric properties can be obtained for all
compositions by pressureless sintering in air. Lead-free piezoelectric ceramics K0.5Na0.5NbO3 with the relative density of 94.5% have been synthesized by solid state process. In addition, the pure KNN ceramics sintered at 1100oC showed optimized densification and piezoelectric properties (ρ = 4.4 g/cm3 and Tc = 415 oC).
