(0.85−x)Pb(Mg1/3Nb2/3)O3–0.10Pb(Fe1/2Nb1/2)O3–0.05PbZrO3xPbTiO3 [(0.85−x)PMN–0.10PFN–0.05PZxPT] polycrystalline ceramics with morphotropic phase boundary (MPB) compositions were prepared using the modified columbite precursor method. The phase transitional behaviors, composition‐dependent electrical properties, and temperature‐dependent piezoelectric properties were investigated, respectively. XRD and Raman spectrum analysis indicated that MPB compositions were located around the region with the PT content of x = 0.30–0.34, confirmed by their corresponding dielectric, piezoelectric, and electromechanical properties. The composition with x = 0.32 possessed the optimum properties with dielectric permittivity εr, tangent loss tan δ, piezoelectric coefficient d 33, electromechanical coupling coefficient k p, remnant polarization P r, and coercive field E c of 3432, 0.017, 626 pC/N, 0.56, 29.90 μC/cm2, and 7.23 kV/cm, respectively. The phase diagram mapped indicated that this quaternary system possesses the similar MPB region with that of other binary and ternary systems. The quaternary system PMNPFNPZPT possessed more competitive d 33, k p, and T r−t than that of Fe‐free ternary 0.59Pb(Mg1/3Nb2/3)O3–0.05PbZrO3–0.36PbTiO3 (0.59PMN–0.05PZ–0.36PT) near MPB, exhibiting comparable P r, E c, εr, tan δ, and T c. Temperature‐dependent field‐induced‐strain and the as‐calculated high field d 33 also confirmed higher temperature stability for Fe‐contained PMNPFNPZPT.
