Study on Hydrothermally Prepared Bi4Ti3O12 Nanoparticles

Abstract

Abstract: The influences of hydrothermal conditions (including starting materials, reaction temperature and time) on
crystal structure and morphologies of Bi₄Ti₃O₁₂ particles, were discussed. Bi₄Ti₃O₁₂ nanocrystalline particles were hydrothermally synthesized in the range of 80～230℃, for 2～12h from Bi(NO₃)₃·5H₂,
TiCl₄ and NaOH solution. The XRD results reveal that the Bi₄Ti₃O₁₂ nanoparticles obtained possess a typical bismuth layered perovskite structure.
TEM microphotographs show that the Bi₄Ti₃O₁₂ nanoparticles are tabular, and their average length is about 200 nanometers.

Key words: hydrothermal synthesis, Bi₄Ti₃O₁₂, ferroelectric, nanoparticle
