PZT nanoparticles synthesized by sol-hydrothermal method and properties

  • PZT nanopowders were fabricated at low temperature by modified sol-hydrothermal method, and the effects of the sintering parameter such as sintering temperature, keeping time on the density, grain size, piezoelectric and dielectric properties of the PZT ceramic were investigated. The results show that the particle size distribution of the PZT nanopowders synthesized 270℃ is homogeneous with pure perovskite structure (20~30nm). The optimal properties of the obtained piezoelectric PZT ceramic sintered at 1150℃ for 2h are planna electromechanical coupling factor: 0.50, mechanical quality factor: 410, piezoelectric constant: 220pC/N, dielectric constant: 1060, respectively. Compared with conventional solid reaction methods for PZT powders, the advantage of the modified sol-hydrothermal method are low synthesis temperature and high sintering activity of the powders.
