Resumen:
In case of nanostructured ceramics, the presence of a large fraction of grain boundaries (GB) can lead to unusual or better properties. One growing area of investigation is the ionic transport in nanostructured solid electrolytes (nanoionics) In the present work, the electrical properties of nanostructured CeO2-10 mol% Y2O3 and CeO2-10 mol% Sm2O3 ceramics have been studied as a function of grain size by electrochemical impedance spectroscopy (EIS).
