Abstract

Cubic BaTiO3 particles of ca. 100nm in diameter were produced at 25 to 60°C in a highly basic aqueous solution system. The crystalline phase was purely formed by reaction of barium hydroxide and anatase TiO2 nanoparticles under the highly basic condition. The formation of the pure phase at a lower temperature requires a higher concentration of NaOH and a longer reaction period. At room temperature (25°C), the crystalline BaTiO 3 was obtained through the reaction with 5.2 mol/kg of NaOH for 168 h. A specific mesocrystal architecture of BaTiO3 consisting of oriented small units was formed as an intermediate at the initial stage of crystal growth.
