Abstract
A superior piezoelectric coefficient (d33 = 570 ± 10 pC N”1), the highest value reported to date in potassium-sodium niobate-based ceramics, is obtained in (1−x−y)K1−w Naw Nb1−zSbzO3−yBaZrO3−x − Bi0.5K0.5HfO3 ceramics. This high d33 value can be ascribed to the co-existence of “nano-scale strain domains” (1–2 nm) and a high density of ferroelectric domain boundaries. Therefore, ternary KNN-based ceramics demonstrate the potential for applications. As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials are peer reviewed and may be re-organized for online delivery, but are not copy-edited or typeset. Technical support issues arising from…
