Abstract


The BaTiO3 powders were synthetized by the hydrothermal method in the alkaline solution using the TiCl3 and BaCl2 like precursors. The Ba/Ti initial ratios effect on the formation of BaTiO3 phase was investigeted versus time (at 150°C). The results showed that BaTiO3 powders have right stoichiometric (approximate 1), homogeneous morphology and grain sizes are in the range of 80 - 100 nm.
