Abstract: Complex perovskite-like phase of lead zirconate titanate, Pb(Zr,Ti)O3 (PZT) ceramics were fabricated with a mixed oxide synthetic route of zirconium titanate (ZrTiO4 ) and lead oxide (PbO) precursors. The effects of sintering conditions on phase formation, densification and dielectric response of PZT ceramics have been investigated using XRD, SEM, EDX and dielectric measurement techniques. The experimental results show that the densification of the PZT ceramics with density 97 % theoretical density, without any sintering additives, can be achieved with appropriate sintering condition (the optimum sintering condition has been identified as 1,225°C for 4 h). The dielectric properties increases with increasing sintering temperature and grain size. However, over 1250 °C, dielectric properties decreased due to PbO vaporization.
