Abstract

Barium titanate (BaTiO₃) ceramics with various grain sizes from 0.7 to 13 μm were prepared by a conventional sintering method and a two-step sintering method. The permittivity of the BaTiO₃ ceramics with an average grain size of 1.1 μm exhibited a maximum around 8,000. By ultrawide range dielectric spectroscopy, the domain-wall contribution to the permittivity was investigated. For the BaTiO₃ ceramics with grain sizes over 1 μm, the dipole and ionic polarizabilities were enhanced by the high domain density. In contrast, for the BaTiO₃ ceramics with grain sizes below 1 μm, these polarizabilities were weakened.
