Abstract

This paper investigated the dielectric relaxation phenomena on ultrafine BaTiO₃. The ultrafine BaTiO₃ particles were prepared by hydrothermal method with a size ranging from 100 nm to 260 nm. The precursors used in the preparation were Ba(OH)₂·8H₂O powder and TiO₂ powder. Temperature dependence of dielectric constant at various frequencies was experimentally investigated. The dielectric relaxation phenomena was successfully observed by studying the temperature spectra of dielectric properties that the dielectric peak as a function of temperature T_m is no longer the same, it shifts to the lower temperature with an increase of the frequency. It was also observed that the dielectric constant decreases with an increase of average particle size. Some possible reasons for the dielectric relaxation phenomena on ultrafine BaTiO₃were discussed in this study.
