Abstract

In this study, dielectric and piezoelectric properties of 0.4[0.1Bi(Ni$\_$1/2/Ti$\_$1/2/)O$_3$0.9Pb(Ni$\_$1/3/Nb$\_$2/3/)O$_3$]-0.6(PbZr$\_$y/Ti$\_$1-y/)O$_3$ceramics with Zr/Ti ratio were observed. As a results, structure of the ceramics with ZrO$_2$(y) 0.425 and 0.45 was MPB. Electromechanical coupling coefficients k$\_$p/, k$\_$31/ of the BN$\_$162/ specimen were 57.2%, 35.6% and piezoelectric constants d$\_$33/, d$\_$31/ were 720, 298[x10$\_$-12/C/N).
