Abstract: Hydrogels BaO⋅TiO2 ⋅ xH2O were prepared by the coprecipitation of Ba2+ ions and Ti(IV) peroxocomplex with solution of NH3. The process of precipitation was followed potentiometrically. The stoichiometric coprecipitation was achieved at pH >12. The BaTiO3 phase formation starts at the temperature approximate to 600°C.
