چکیده انگلیسی
The LiNiV O4 fine powder has been synthesized by chemical “pyrophoric reaction process”. The formation of LiNiV O4 is confirmed by X-ray diffraction analysis. X-ray analysis shows that the compound has cubic crystal structure with lattice constant (a=8.2243(2)Ã
). Microstructure of the sintered pellet is identified by taking the field emission scanning electron microscopy (FE-SEM) pictures, which reveals the grain size as â¼0.2-2 μm. Electrical properties are measured using complex impedance spectroscopy technique. Bulk contribution to electrical response is identified by the analysis of complex plane diagrams. The activation energy calculated from Ïdc vs 103/T graph is â¼0.06 eV (25-225 âC) and â¼0.55 eV (225-375 âC). Complex modulus study shows non-Debye type (polydispersive) conductivity relaxation in the compound.
