Abstract: | The dielectric and piezoelectric properties of the (Pb0.985Bi0.01)(Ni1/4Zn1/12Nb2/3)x- (ZrσTi1-σ)1-xO3 piezoelectric ceramic system (0.2 ≤ x ≤ 0.7, 0.1 ≤ σ ≤ 0.9) were systematically investigated. The results showed that, after poling, the dielectric constant, ε

T
, increased for the tetragonal compositions but decreased for the rhombohedral compositions. Furthermore, high values of ε

T
and piezoelectric modulus, d
31 were found for the compositions along the extension of the morphotropic phase boundary. The highest values of the planar
electromechanical coupling factor, K
p, and the piezoelectric modulus, d
31, were found to be 0.70 and − 274 × 10-12 C N-1, respectively. The Curie temperature, remanent polarization, coercive field and the lattice constants of the a and c axes in relation to the Pb(Ni1/3Nb2/3)O3 content and the Zr/Zr + Ti ratio were also determined.
