STUDY OF HYDROTHERMAL SYNTHESIS AND PROPERTIES OF Bi₂Fe₄O₉

Highly oriented Bi 2 Fe 4 O 9 nanosheets can be fabricated with Fe(NO 3 ) 3 ⋅ 9H 2 O and Bi(NO 3 ) 3 ⋅ 5H 2 O using the low-temperature hydrothermal method. The as-prepared powders are characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM), which exhibit an excellent orientation along the (00l) planes. The leakage current density and dielectric properties of the...
