Title: Grain size modulation on BaTiO{sub 3} nanoparticles synthesized at room temperature

Abstract

A new method is developed to synthesize massive BaTiO{sub 3} nanoparticles directly at room temperature. With this method, the synthesis efficiency is improved and mass preparation can be realized. Also, the grain size of the as-prepared nanoparticles can be modulated from several nanometers to 40 nm through proper selection of the content of water and the alkanol chain length of the dispersant. It was found that smaller water content and a larger alkanol chain length of the dispersant will lead to a finer grain size. The mechanisms of the grain size modulation of BaTiO{sub 3} nanoparticles are also discussed. - graphical abstract: This paper offers a direct facile approach to BaTiO{sub 3} nanoparticles at room temperature with a large quantity. The grain size can be modulated purposefully. Highlights: > Room temperature synthesis of BaTiO{sub 3} nanoparticles with large scale is realized. > Grain size can be controlled purposefully. > Effect of content of water on crystallization of BaTiO{sub 3} is revealed. > Influence of alkanol chain length of the dispersant is found.
