Synthesis and ion dynamics studies of nanocrystalline Mg stabilized zirconia

M Vijayakumar, S Selvasekarapandian… - Physica B: Condensed …, 2003 - Elsevier
The nanocrystalline Mg stabilized zirconia with 18 and 22mol% were prepared by co-
precipitation method. The formation of the mixed cubic and tetragonal phases have been
observed from X-ray diffractogram studies. The impedance Cole–Cole plot shows the grain
interior and grain boundary resistance contributions. The conductance spectra show the DC
plateau and dispersive region suggesting the correlated hopping motion of ions. The charge
carrier concentration is found to be increasing with Mg doping and hence high conductivity …
