Ceramic and electrical properties and crystal structures of the system Pb(Mg l/3 Nb 2/3 ‐ PbTiO 3 ‐PbZrO 3 are described. The system is composed of three crystal phases at room temperature: pseudocubic, tetragonal, and rhombohedral. A high dielectric constant and radial coupling coefficient and low resonant resistance were obtained for the compositions near the morphotropic transformation. The composition Pb(Mg l/3 Nb 2/3 ) 0.4375 Ti 0.4375 Zr 0.125 O 3 had the lowest temperature coefficient of resonant frequency.
