Ceramic and piezoelectric properties of the Pb(Co 1/3 Nb 2/3 )O 3 ‐PbTiO 3 ‐PbZrO 3 system were investigated. The system contains rhombohedral, tetragonal, and pseudocubic phases at room temperature. The triple point is at 0.07Pb(Co 1/3 Nb 2/3 )O 3 ‐0.43PbTiO 3 ‐0.50PbZrO 3 . High dielectric constants (750 to 1500) and radial coupling coefficients (40 to 45%) and low average temperature coefficients of resonant frequency (of the order of 10 ‐6 °C) were obtained for compositions near the morphotropic phase boundary.
