Cobaltous Oxide Point Defect Structure and Non-Stoichiometry, Electrical Conductivity, Cobalt Tracer Diffusion

The point defect equilibria of cobaltous oxide (Coi_äO) as a function of temperature and oxygen potential are analyzed. Majority point defects are electron holes and differently charged vacancies in the cation sublattice. On the basis of the derived defect model it is possible to quantitatively describe literature data for non-stoichiometry, electrical conductivity and cation tracer diffusion. Additional cation tracer diffusion coefficients were measured at temperatures between 1000 and 1400 °C as a function of the oxygen activity covering the entire 1 atm stability range of this oxide.
