Ceramics in PYBZT-PMS system with formula Pb1−xYx/2Bix/2[(Zr0.53 Ti0.47)0.92–(Mn1/3 Sb2/3)0.08]O3 (x = 0–0.00625) were prepared by the conventional solid state sintering. The evolution of microstructure and corresponding electrical properties of PYBZT-PMS samples were systematically studied. Phase transition from rhombohedral to tetragonal structure was identified by Raman spectra and XRD results, and the coexistence of two phases was observed near the composition range from x = 0.0025 to 0.005. Scanning electron micrographs of the samples show uniform distribution of grain and grain boundaries. The optimum electrical properties of PYBZT-PMS such as εr = 1119.397, tanδ = 0.01535, Tc = 390 °C, ρ = 7.82 g/cm3, σ = 0.709 (Mohm m)−1, Qm = 525.232, and KP = 0.639 were obtained at x = 0.00375.
