摘要Abstract: Lead-free piezoelectric ceramics (K0.5Na0.5)NbO3 with the relative density of 94.5% have been synthesized and investigated by solid state method in this letter. The pores cannot be eliminated easily because the shapes of the grains for pure KNN ceramics are quadrate. Pure KNN ceramics sintered at 1100ºC reveal optimized densification (4.4 g/cm3) and Curie temperature (415ºC).
