Abstract

(K, Na, Li)NbO3 (KNN) ceramics was reported to show excellent piezoelectric properties and has been regarded as a candidate of lead-free piezoelectric materials. However, the effects of hard additives on the properties have not been studied intensively so far. In this study, KNN ceramics with hard character dopants doped have been prepared by a solid state reaction and their electrical properties were examined.
