abstract The innovative solid state step-sintering reaction technique was used to fabricate lanthanum doped bismuth-nickel ferrite perovskite oxide (Bi1.7La0.3Ni2Fe2O8). The physical features, surface shape, grain dispersion topography, spatial frequency spectrum and temperature-frequency dependent dielectric properties were investigated. By means of X-ray diffraction, the W-H approach, SEM morphology, histograms and EDAX color mapping, the attributes of the produced material concerning crystallite size (47.5 nm), strain (0.00152), dislocation density(4.43×1014 m-2), polycrystalline grain (0.01 μm-2μm) orientations, uniformly aligned grain texture, modest isotropy (50.45 %) and elemental compositions were evaluated. Impedance spectroscopy analysis of this material provides insight into the dielectric dispersion. The low dielectric loss in the high frequency regime signifies negligible dielectric energy dissipation. The findings support the idea that Bi1.7La0.3Ni2Fe2O8 might be a promising mixed metal oxide-based ceramic component for potential multifunctional electronic device applications.
