Influence of the synthesis and sintering conditions on the microstructure and electrophysical properties of lead-free (K0.5Na0.5)NbO3-based piezoelectric ceramics is investigated. Synthesis method, which makes possible to reduce synthesis temperature and regulate particles’ size in synthesized powder, is developed. Nanostructure lead-free piezoelectric ceramics with the Curie point TC???400?С is obtained. Piezoelectric sensitivity g33 of the obtained ceramics almost four times exceeds the sensitivity of the best PZT-based ceramics.
