Paper Title:
Microstructure and Dielectric Properties of BaTiO3-Based Ferroelectric Materials
  Abstract

The microstructure and dielectric properties of BaTiO3-based ceramics and films were investigated. In BaZr0.2Ti0.8O3 ceramics domains with herribone, lamellar and “water-mark” characters are observed and 90◦-domain has not been observed in large grain size sample. It is shown that the average grain size and the remanent polarization of doped BZT ceramics decrease with the increasing of Al content. The dielectric constant and tunability of the BaZr0.2Ti0.8O3 films using inorganic zirconate are 113 and 10.2%, respectively. It is found that nanowires of BaTiO3 annealed for 2.5 min are very clear-cut, orderly and almost uninterrupted.
