Abstract

Phase-pure KNN (K0.5Na0.5NbO3) was synthesized from Rochelle salt and niobium pentoxide through solid-state route and the synthesized powder was sintered at 1130 degrees C to get dense KNN ceramics. After polarization fatigue test, it was found that the d(33), k(P) and remanent polarization (P-rem) of KNN decreased substantially. The reduction of the aforesaid parameters after fatigue was much higher in comparison to that of soft PZT (Navy type VI) tested under identical conditions. The possible reason behind such behaviour has been delineated.
