Abstract

Tetragonal barium titanate single crystal was synthesized by hydrothermal treatment of Ba-Ti-OH precursor slurry with 10 vol% ethylene glycol aqueous solution. Oxygen site was partially occupied by hydroxide ion in the synthesized barium titanate. The tetragonality of synthesized crystal disappeared by heat treatment, indicating that substituted hydroxyl group stabilized the tetragonal crystalline structure. The dielectric constant of prepared barium titanate particles was measured by slurry method using propylene carbonate as a dispersion medium. The results from dielectric constant of slurry indicated that the intermediate structure between tetragonal and cubic is effective for high dielectricity.
