The effect of co-doping of Pb1–xYx[(Zr0.53Ti0.47)1–xNbx]O3 bulk materials (0 ≤ x ≤ 0.03) with Y3+ ionsand Nb5+ on their dielectric and piezoelectric properties o was investigated. Samples fabricated by conventionaloxide mixing (OM) were sintered at 1250 °C for 2 h in a Pb-rich atmosphere. During the tetragonal–rhombohedral transition in the doped PZT ceramics a negligible effect was observed after additionsof Y3+ and Nb5+ ions. The co-doping with both ions was noted to inhibit grain growth and promote densificationand electrical properties. The optimal doping level was found to be at x = 0.015, for which theelectric permittivity of 907, the piezoelectric constant of 323 pC/N, g33 of 40 mV/N, Qm of 272 and the
