Facile synthesis of nanorods of tetragonal barium titanate using ethylene glycol
Source abstract
Abstract
Abstract Tetragonal barium titanate (BaTiO 3 ) 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 BaCl 2 and TiCl 4 . When the above aqueous slurry was heated with water only at 200 °C, cubic BaTiO 3 nanocrystals formed, whereas tetragonal BaTiO 3 nanorods were obtained when heated with 10 vol% ethylene glycol. The crystallization of cubic BaTiO 3 via dissolution–reprecipitation of precursor could be suppressed by the addition of ethylene glycol, resulting in the formation of tetragonal BaTiO 3 under hydrothermal treatment at 200 °C.
