A novel approach to synthesize, studies of structural and electrical characteristic of Bi(Ni0.30Ti0.30Fe0.40)O3 nanoceramics

[摘要] In this study, we report a novel approach to synthesize the Bi(Ni0.30Ti0.30Fe0.40)O3[arbitration BNTF30/40] nanoceramics by standard ceramic method at an ambient temperature of 1013 K. Carbonates and oxides powder were utilised as a raw materials in an appropriate stoichiometric amounts. X-ray diffraction pattern assigned that the BNTF30/40 sample presents a single phase of orthorhombic symmetry. The crystallite size obtain from X-ray data suggests the formation of BNTF30/40 nanoceramics in the range between 20 to 45 nm. Bulk density of the prepared pallets were measured and found to be more than 94 percent. The basic characterization tools have been used respectively with Field Emission Scanning Electron Microscope and Spectroscopy based techniques to obtain the correlation between surface morphology and electrical characteristic of specimen sample. Electrical characteristic of the as- synthesized material was studied in the experimental temperature range between RT to 623 K at different operated frequency (25 kHz - 500 kHz).
