Effect of Ferroelectric Long-Range Order on the Unipolar and Bipolar Electric Fatigue in Bi1/2Na1/2TiO3-Based Lead-Free Piezoceramics

Effect of Ferroelectric Long-Range Order on the Unipolar and Bipolar Electric Fatigue in Bi1/2Na1/2TiO3-Based Lead-Free Piezoceramics

The fatigue behavior of the lead-free piezoelectric Bi1/2Na1/2 TiO3–BaTiO3K0.5Na0.5NbO3 (BNT-BT-KNN) under bipolar and unipolar electrical loading is investigated. Special attention is paid to the effect of a decreasing ferroelectric order which was affected by an increase in KNN-content. It is foun...
