Abstract
In this study, Pb(Zr0.52� Ti0.48)O3 nanopowders were synthesized via sol-gel process. Particle morphology, crystalline phases and thermal behavior were characterized by scanning electron microscopy, X-ray diffraction and simultaneous thermal analyzer, respectively. The X-ray diffraction pattern showed perovskite phase clearly. The non-isothermal activation energy for the perovskite crys- tallization in Pb(Zr0.52� Ti0.48)O3 gel powders was 224.91 kJ mol -1 . Both growth morphology parameter (n) and crystallization mechanism index (m) are close to 3.0, indicating that the bulk nucleation is dominant in the perovskite PZT formation. To determine dielectric prop- erties, the calcined Pb(Zr0.52� Ti0.48)O3 nanopowders were pressed using uniaxial press. It was found that the Pb(Zr0.52� Ti0.48)O3 disks, by sintering at 1,200 C for 2 and 10 h, and at 1 kHz frequency, had 966 and 1,490 of the dielectric constant, respectively.
