Abstract
The dielectric properties of the (1−x)NaNbO3−x KNbO3 and (1− x)NaNbO3−x PbTiO3 systems are investigated. The antiferroelectric-ferroelectric transition regions are determined. It is established that in the (1−x)NaNbO3−x KNbO3 system the antiferroelectric phase is stable for x≤0.01 and the ferroelectric phase is stable for x≥0.0175; the transition from one phase into another occurs in the concentration range 0.01<x<0.0175. In the (1− x)NaNbO3−x PbTiO3 system the transition region lies in the range 0.07<x<0.11.
