The phase diagram of the system (1- x-y ) NaNbO 3 – x KNbO 3 – y CdNb 2 O 6 ( y =0.25, x =0.05÷0.20) is constructed. The agreement between the microstructure and the phase diagram of the system is demonstrated. A decrease in the polarization characteristics up to the phase transition temperature is detected. The formation of extrema d 33 ( E ) in the region of the inflection point on the ascending branch of the half-period S 33 is revealed. A correlation has been established between the internal structure (crystalline, domain, grain, defect), fundamental electromechanical and polarization properties for solid solutions of the studied system.
