Abstract

In this study, microstructure and piezoelectric properties of PSN-PZT ceramics modified with BiFeO$_3$ were investigated as a function of PNW substitution. With the increase of PNW substitution, tetragonality, Curie temperature and mechanical quality factor were decreased but grain size and electromechanical coupling factor(kp) was gradually increased. At 4 mol[%] PNW substitution, maximum kp of 0.567 was obtained.
