The purpose of the present study is to consider the mechanism of oxidation of zirconia and related charge transfer at the oxygen/zirconia interface, focusing on yttria-stabilised cubic zirconia. The study considers unresolved problems concerning the electrochemistry of the oxygen/zirconia interface at elevated temperatures and formulates the relevant questions to be addressed. The present paper outlines the research strategy for addressing these questions. The basic properties of yttria stabilised zirconia, such as electrical properties and oxygen diffusion, are summarised.
