| description | This paper investigates the processes of phase formation of solid solutions of (1 − <i>x</i>)BaTi<sub>0.85</sub>Zr<sub>0.15</sub>O<sub>3</sub> − <i>x</i>AgNbO<sub>3</sub> where <i>x</i> = 0, 0.03, 0.06, 0.09. The optimal temperatures of synthesis and sintering are determined. From the results of X-ray diffraction analysis, it follows that all solid solutions have a perovskite-type structure. Analysis of the microstructure showed that the average grain size decreases at concentrations <i>x</i> = 0.03 and 0.06. Correlations between the cationic composition and dielectric characteristics of the studied solid solutions have been established. The values of the total stored energy and efficiency are determined. The maximum stored energy was found for a solid solution with <i>x</i> = 0.03 and amounted to 0.074 J∙cm<sup>−3</sup> with an efficiency of 76.5%. |
