| Summary: | The authors synthesized samples and studied the structure of piezoelectric ceramics based on sodium and lithium niobates (Li0,1Nao,9)NbO3 with various technologies for the synthesis of sodium niobate material. A comparative study of the structure and dielectric properties of the obtained samples was carried out.. A significant dependence of grain formation during sintering of the samples on the synthesis temperature of the NaNbO3 composition is shown. It was found that the temperature of the phase transition strongly depends on the temperature of the first synthesis of the sodium niobate ( Tmax ~ 375 °С if the first synthesis temperature was 650 °С; Tmax = 425 °С if the first synthesis temperature is 700 °С). |
