On the basis of eutectic behavior of PbTiO3--PbZrO3--Bi(Zn0.5Ti0.5)O3 ternary system, perovskite-structured Pb0.98Bi0.02Zr0.51Ti0.48Zn0.01O3 ceramics were able to be prepared using conventional electronic ceramic processing at low sintering temperature compatible with Ag as inner electrode materials, promising for co-firing technology to fabricate monolithic multilayer piezoelectric transducers. The dependence of its piezoelectric properties on sintering temperature and various dopants were investigated experimentally and a piezoelectric property with dielectric constant of $\varepsilon_{33}^{T}/\varepsilon_{0}=1190$, dielectric loss of $\tan\delta=0.6$%, piezoelectric coefficient of $d_{33}=270$ pC/N, planar coupling coefficient of $k_{\text{p}}=0.54$, thickness coupling coefficient of $k_{\text{t}}=0.46$ and Curie temperature of $T_{\text{c}}=346$ °C was obtained for the 0.5% Co-doped Pb0.98Bi0.02Zr0.51Ti0.48Zn0.01O3 ceramics sintered at 950 °C.
