Abstract

Low temperature synthesis of BaTiO3 thin films was performed under hydrothermal conditions below 80°C. Titanium metal, polycrystalline titanium oxide, and polystyrene (coated with a metallo-organic titanium precursor by a sol-gel process) were used as substrate materials. The reactions between the substrates and aqueous Ba(OH)2 solution took place at different time intervals from 10 minutes to 48 hours. The formation mechanisms of BaTiO3 was investigated by electron microscopy techniques during the reaction sequence. It is proposed that the nucleation and growth of crystalline BaTiO3 occur within an amorphous intermediate phase on Ti-metal and polystyrene substrates. However, thin film of BaTiO3 does not form on the surface of the sintered polycrystalline TiO2 under similar reaction conditions.
