Effect of nano ZnO additive on the microstructure and electrical properties of potassium-sodium niobate lead-free piezoelectric ceramics

Effect of nano ZnO additive on the microstructure and electrical properties of potassium-sodium niobate lead-free piezoelectric ceramics

The present work concerns the effect of adding nano sintering aids on microstructure, densification and electrical properties of KNN piezoceramics. Lead free (K0. 5 Na 0 .5) NbO 3 (KNN) + x mol % nano ZnO have been prepared by conventional mixed oxide method. A single phase perovskite crystal struct...

Zusammenfassung:The present work concerns the effect of adding nano sintering aids on microstructure, densification and electrical properties of KNN piezoceramics. Lead free (K0. 5 Na 0 .5) NbO 3 (KNN) + x mol % nano ZnO have been prepared by conventional mixed oxide method. A single phase perovskite crystal structure obtained for all compositions. Our results reveal that a small amount of nano ZnO can improve the densification and electrical properties of KNN ceramics.
