This paper studies the dielectric spectra of solid solutions(SS)of the system(1−x−y)NaNbo_(3)-xKNbo_(3)-yCdNb_(2)o_(6) y=0.075,x=0.05÷0.30 in the temperature range(10÷900)*** formation of a local maximum was established in the interval(260÷300)K at small x values,which,as KNbo3 increases,is gradually blurred and becomes an inflection *** in SS with x=0.05÷0.10,the shift of the maxima of dependencesε′/ε_(0)(T)andε″/ε_(0)(T),depending on the frequency of the electric field at the temperature ranges(300÷304)K and(258÷271)K,is not related to *** anomaly may indicate a crystallographic disorder to A and B *** conclusion is made about the expediency of using the obtained results for the development of functional ferroactive materials.

The paper reports results on the complex study on ferroelectric ceramics that represent solid solutions containing components with a perovskite-type or columbite-type *** solutions of a three-component(1−x−y)NaNbo_(3)−xKNbo_(3)−yCdNb_(2)o_(6) system are manufactured at x=0.05-0.20 and y=*** structures in ceramic grains are *** consistency between experimental and calculated results is examined for coexisting phases split into non-180°domains(mechanical twins)in the solid solution with x=0.15.A correlation between the internal structure(crystal,domain,granular,and defect)and fundamental electromechanical and polarization properties is stated for the studied three-component solid solutions.
