Synthesis of Na0.5Bi0.5TiO3 Microcubes via a Cr3+-Assisted Hydrothermal Route
Abstract:
Na0.5Bi0.5TiO3 microcubes with the side size ca. 20-30um were successfully fabricated by a Cr3+-assisted hydrothermal method. The obtained samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results show that Cr3+ played a significant role in the formation of Na0.5Bi0.5TiO3 microcubes. Possible mechanisms for the growth of Na0.5Bi0.5TiO3 microcubes are discussed. The results presented in this study would be important in investigating the correlation between morphology and basic physical properties, and may offer a route to control the morphology and size of crystals.
