Defects and Transport Properties of Metal Oxides

摘要

The paper gives an overview of different types of defects and defect structures in metal oxides and transport properties such as diffusion and electrical conductivity. Point defects (vacancies, interstitials, impurity and dopant ions, hydrogen ions, a.o.) and corresponding defect structures are described by defect equations and equilibria. Oxides of common use metals and which are of particular interest in many aspects of high-temperature oxidation of metals, e.g., cobalt and nickel oxides, chromia, alumina and silica, are used as examples in describing defect structures and transport properties.
