Non-Stoichiometry and Defect Structure of FeO

  • Chapter

Part of the book series: NATO ASI Series ((ASIC,volume 276))

Abstract

The non-stoichiometry in wustite (Fe1-yO) is considered in terms of the 4:1 cluster model. It has been shown that the ionisation degree of the cluster above 1173 K is -5. The Debye-Hückel theory is applied to determine the equilibrium constant of the cluster formation. It has been demonstrated that the cluster model is well consistent with the free partial molar enthalpy of oxygen ΔH(O2) reported for Fe1-yO.
