N2 - Thin films of cubic BaTiO3 were processed hydrothermally at 40°-80°C by reacting thin layers of titanium organometallic liquid precursors in aqueous solutions of either Ba(OH)2 or a mixture of NaOH and BaCl2. All films (thickness ∼ 1 μ) were polycrystalline with grain sizes ranging from nano- to micrometer dimensions. BaTiO3 formation was facilitated by increasing [OH-], [Ba2+], and the temperature. The film structure was related to the nucleation and growth behavior of the BaTiO3 particles. Films processed at relatively low [OH-], [Ba2+], and temperatures were coarse grain and opaque, but increasing [OH-], [Ba2+], and temperature caused the grain size to decrease, resulting in transparent films.
