This study describes the microstructure, crystal structure, dielectric and piezoelectric behavior of 0.1Pb[Fe_1/2Nb_1/2]O₃-0.9Pb[Zr_xTi_(1–x)]O₃ (x = 0.49-0.55) ceramics synthesized by solid-state reaction. Compositions were sintered at 1180^oC for 120 min. Dense and uniform microstructure was seen through microstructural analysis. XRD pattern confirmed the co-existence of tetragonal and rhombohedral perovskite phases in these compositions where 0.51 ≤ x ≤ 0.53. Compositions with 0.51 ≤ x ≤ 0.53 resulted in the optimum values of properties, viz. dielectric constant (ϵ_rr) of 1150, piezoelectric coefficient (d₃₁) of 95x10^–12 C/N, piezoelectric voltage constant (g₃₁) of 70x10^–3 mV/N and the coupling factor (k_p) value of 0.67. Results indicated that this material composition could be suitable for power harvesting and sensor applications.
