Dimension effects on the dielectric properties of fine BaTiO sub(3) ceramics

It is found that the core-shell structured grains are easy to produce for fine grain doped BaTiO sub(3) ceramics in the sintering process. We study the influence of the core-shell structure on the Curie-Weiss temperature and dielectric properties of BaTiO sub(3) ceramics by using effective medium ap...

Zusammenfassung:It is found that the core-shell structured grains are easy to produce for fine grain doped BaTiO sub(3) ceramics in the sintering process. We study the influence of the core-shell structure on the Curie-Weiss temperature and dielectric properties of BaTiO sub(3) ceramics by using effective medium approximation (EMA). Considering the second approximation, the dielectric properties of fine grain doped BaTiO sub(3) ceramics are consistent with experimental data.
