The physical and electrical properties of xPb(In1/2Nb1/2)O3(PIN)–yPb(Mg1/3Nb2/3)O3(PMN)–zPbTiO3(PT) (PIMNT 100x/100y/100z) ternary ceramic materials near the morphotropic phase boundary (MPB) were investigated. The MPB follows an almost linear region between the PIMNT 63/0/37 and PIMNT 0/68/32 MPB compositions of the binary systems. All the sintered ceramics show a complete perovskite structure. The maximum dielectric constants decrease as the function of PIN content increases. The maximum electromechanical coupling factor, kp=67.6%, is found at PIMNT 24/42/34, where dielectric constant, ε33T/ε0=2,120, piezoelectric constant, d33=505 pC/N, and Curie temperature, Tc=219°C, are obtained.
