Low-frequency dispersion behavior of impedance spectra of Li0.867Nb0.988Ni0.098O3 ceramic



Abstract. Ceramic material sample of Li0.867Nb0.988Ni0.098O3 was prepared by solid-state reaction method and their impedance spectra were measured in the frequency range from 1Hz to 10MHz and temperature range from 400 to 800°C. The obtained data were analyzed by means of electric impedance formalism. Two dielectric relaxation processes were revealed in the frequency range and temperature interval of the measurements. One of these relaxations appearing in law frequencies was associated with grain boundaries and/or the interfacial polarization. Whereas the other appearing at high frequencies is consistent with the grain effect.
