The Research on Hydrothermal Synthesis of Na0.5Bi0.5TiO3 Powder from TiCl4
Abstract: Different morphologies of Bismuth Sodium Titanate (Na0.5Bi0.5TiO3, abbreviated as NBT) powders have been successfully prepared via a hydrothermal method using titanium tetrachloride (TiCl4), bismuth nitrate (Bi(NO3)3•5H2O), sodium hydroxide (NaOH) as titanium, bismuth, sodium source, respectively, and sodium hydroxide (NaOH) as mineralizing agent, too. The effect of reactive parameters, including NaOH concentration, reaction temperature and reaction time on the powders morphologies, was studied. The results show that: NaOH concentration is the main parameter which affects the morphology of NBT powders, and when the NaOH concentration is 14 M, hydrothermal temperature and hydrothermal time affect more on the crystallinity of NBT powders, and the effect they make on the morphology of NBT powders is not evident.
