Tetragonal barium titanate (BaTiO3) nanorods were synthesized from hydroxide precursor by a hydrothermal/solvothermal method with 10 vol% ethylene glycol as solvent. The hydroxide precursor slurry was prepared by the addition of 10 M NaOH to a mixed solution of BaCl2 and TiCl4. When the above aqueous slurry was heated with water only at 200 °C, cubic BaTiO3 nanocrystals formed, whereas tetragonal BaTiO3 nanorods were obtained when heated with 10 vol% ethylene glycol. The crystallization of cubic BaTiO3 via dissolution-reprecipitation of precursor could be suppressed by the addition of ethylene glycol, resulting in the formation of tetragonal BaTiO3 under hydrothermal treatment at 200 °C.
