The doped Pb(Zr0.52Ti0.48)O3 system with Nb5+ and Sr2+ were obtained by solid state reactions. The influence of nature of dopants on structural and microstructural properties were analyzed by XRD and SEM techniques and were also investigated the obtained dielectric and piezoelectric properties. The XRD analyzes and the SEM images highlighted the obtaining of homogeneous tetragonal structures, of the perovskite type. The physical (ρa), dielectric constant (ɛr) and piezoelectric (kp) properties of the doped PZT systems were investigated. The Nb5+ doped Pb(Zr0.52Ti0.48)O3 system presented the ɛr = 488 and kp = 0,52. Sr2+ substitution for Nb5+ doped Pb(Zr0.52Ti0.48)O3 reduced the Curie temperature (from 420°C to 360°C), increased the dielectric constant at 1180, and also decreasing the kp (0,39).
