Abstract: The authors synthesized samples and studied the structure of piezoelectric ceramics based on sodium and lithium niobates Li_1-xNa_xNbO₃. A significant dependence of the grain formation during sintering of the samples on the ratio Li / Na is revealed. Based on the analysis of the structure and measurement of the temperature dependence of the dielectric constant, the optimal compositions for practical application are proposed Li_0,1Na_0,9NbO₃ and Li_0,4Na_0,6NbO₃.

Keywords: piezoelectric ceramics, lead-free materials, grain structure.
