Crystal structure, phase purity and microstructure were examined through X-ray diffractometry and scanning electron microscopy, respectively. The crystallographic results show the formation of single-phase solid solutions for all compositions except x = 10 mol%. The BF-BT modification through BZT instigates variation in grain size, enhancement in Curie temperature (TC) and field induced polarization and strain response. Large field induced strain of ∼0.24% at low driving field along with a small hysteresis of ∼38% was observed for 2 mol% BZT modified BF-BT ceramics. These investigated results signpost the potentiality of BF-BT-xBZT ceramics in high temperature piezoelectric device applications.}, number={13}, journal={JOURNAL OF THE EUROPEAN CERAMIC SOCIETY}, author={Ryu, Gyung Hyun and Hussain, Ali and Lee, Myang Hwan and Malik, Rizwan Ahmed and Song, Tae-Kwon and Kim, Won-Jeong and Kim, Myong-Ho}, year={2018}, month={Oct}, pages={4414–4421} }
