Abstract:
The main purpose of present study is to synthesis nano-sized BaTiO powders using Ba(OH) and TiO by stirred reactor hydrothermal process with and without rGO (reduced Graphene Oxide). BaTiO powders are prepared at various reaction temperature and time in the presence or wihtout rGO already obtained via chemical exfoliation. X-ray diffraction, Raman spectroscopy, Impedence and scanning electron microscopy (SEM) are used to characterize the synthesized BaTiO powders. XRD and Raman spectroscopy data revealed that cubic phase nano-sized BaTiO powders are successfully obtained in all the cases. In case of BT without rGO at elevated temperature 160C revealed the presence of tetragonal phase while at the same temperature with rGO obtained BT has the cubic phase with well defined morphology and crystallanity. Hence the presence of rGO restricted the BT to its cubic phase while the crystallanity and morphology improved with exact stichiometry.
