Preparation of Ceramic Nanocomposite with Perovskite Dispersoid

  • T. Nagai (a1), H. J. Hwang (a2), M. Sando (a2) and K. Niihara (a3)


In order to introduce ferroelectricity into structural ceramics, we synthesized novel ceramic composites containing submicron sized perovskite-type ferroelectrics (ceramic / perovskite-type ferroelectrics nanocomposites). Although perovskite compounds easily react with other ceramics, MgO/BaTiO3 nanocomposites were successfully fabricated using conventional sintering technique. The microstructure of nanocomposites and the phase stability of the dispersed BaTiO3 particulate are discussed.
