Abstract

In this paper, piezoelectric and dielectric properties of 0.9PbZr x Ti1−xO3-0.1PbNi1/3Sb1/3Nb1/3O3 were studied as a function of Zr/Ti mole ratio(x) for application to piezoelectric actuator. Also, microstructure and crystalline phase are investigated by using SEM and XRD, respectively. As a results, the substitution of Sb5+ to B-site increases the piezoelectric and dielectric properties, and when Zr/Ti mole ratio is 49/51 and ternary mole ration is 0.1(0.9PbZr0.49Ti0.51O3-0.1PbNi1/3Sb1/3Nb1/3O3), the corresponding composition were found belonging to the Morphotropic Phase Boundary region with electromechanical coupling coefficient(k p ), mechanical quality factor (Qm), permittivity(ε r ) and piezoelectric strain constant(d33) equaled to 63%, 360, 2000 and 470 pC/N, respectively. Sintering temperature was about 1150_∘C and Curie temperature was determined around 290_∘C.
