The complex nonstoichiometry of wüstite Fe 1-z O: review and comments
Abstract : Thermodynamic properties and structural aspects of the nonstoichiometric wüstite Fe1-zO, and its modifications - the so-called pseudo-phases - as functions of departure z from stoichiometry and of equilibrium temperature are reviewed from 1960 to present. The complexity of the equilibrium phase diagram is described in some details. The first order transition W ⇆ W’ is specified on the iron/wüstite boundary near 1185 K. Transitions correlated to the modifications Wi at T(W) > 1185 K and W’j at T(W’) < 1185 K (i and j =1,2,3) are re-examined. Structural determinations based on the characterization of point defects stabilization and of their clustering are reviewed. Additionally, the pseudo-phases are examined based on the transformation of defect clusters or of their mode of distribution (i.e., percolation or superstructure) with the inclusion of changes in electronic charge carriers.
