Abstract
Wüstite (Fe1–xO) is a complex oxide that is invariably non-stoichiometric (0.04 ≳ x ≳ 0.12). Point defects associated with this nonstoichiometry are clustered and result in a modulated crystal structure that has been extensively studied, but is not well understood1–4. Many of the properties of these compounds, such as chemical diffusivity, electrical conductivity and magnetic transitions, seem to be significantly affected by the nonstoichiometry and resulting ordering of defects5–8. We summarize here new and existing data on the elasticity of wüstite; these data indicate virtually no correlation between the bulk modulus and stoichiometry. There appears, however, to be a systematic difference between static and dynamic measurements. This behaviour suggests the presence of a frequency dependence to the bulk modulus that can be ascribed formally to a finite bulk viscosity of Fe1–xO. Such an effect has not previously been described in oxide or silicate minerals, and it is presumably caused by pressure-induced changes in defect ordering and subsequent relaxation within the incommensurate structure of wüstite.
