Abstract

Fine powders of BaTiO3 are synthesized by hydrothermal processing at 250 C for 7 h. Two different starting mixtures were used, TiCl3 + BaCl2 and TiO2 + BaCl2. The size of the resulting crystallites was close to 20 nm in both cases. The powders were formed into ceramic pellets or thick layers. The samples were characterized for microstructure and electrical permittivity. The impact of the microstructure on the electrical properties is emphasized, and is correlated to the powder characteristics and the powder realization process.
