This paper studies the dielectric spectra of solid solutions (SS) of the system (1 − x − y)NaNbO3–KNbO3 –CdNb2O6= 0.075, = 0.05 ÷ 0.30 in the temperature range (10 ÷ 900) K. The formation of a local maximum was established in the interval (260 ÷ 300) K at small values, which, as KNbO3 increases, is gradually blurred and becomes an inflection point. Detected in SS with = 0.05 ÷ 0.10, the shift of the maxima of dependences ′/ 0() and ′′/0 (), depending on the frequency of the electric field at the temperature ranges (300 ÷ 304) K and (258 ÷ 271) K, is not related to relaxation. This anomaly may indicate a crystallographic disorder to A and B positions. The conclusion is made about the expediency of using the obtained results for the development of functional ferroactive materials.This paper studies the dielectric spectra of solid solutions (SS) of the system (1 − x − y)NaNbO3–KNbO3 –CdNb2O6= 0.075, = 0.05 ÷ 0.30 in the temperature range (10 ÷ 900) K.
