Abstract

We report a study of ionic conductivity in the series Y2Ti 2-yZryO7 and Gd2Ti 2-yZryO7 (0≤y≤2) obtained by mechanochemical synthesis. We present a study of oxygen ion dynamics in these materials by Impedance Spectroscopy. The change in dc conductivity and activation energy with Zr content is interpreted in terms of the increase in the number of oxygen vacancies and of structural disorder when increasing Zr content.
