Hydrothermal synthesis and characterization of Bi4Ti3O12 powders
نویسندگان
چکیده
The Bi4Ti3O12 powders were synthesized by a hydrothermal route. The influence of hydrothermal conditions on crystal structures and morphologies of Bi4Ti3O12 particles was studied. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared (FT–IR) spectroscopy and ultraviolet visible (UV-vis) spectroscopy. These results revealed that the Bi4Ti3O12 powders prepared thus possessed a plate-like shape, a typical bismuth layered perovskite structure, and a wide UV-vis absorption peak. Additionally, the formation mechanism of the Bi4Ti3O12 nanoplates was also discussed. ©2009 The Ceramic Society of Japan. All rights reserved.
