Equations of state of FeO and CaO
New shock-wave (Hugoniot) and release-adiabatic data for Feo.940 and CaO, to 230 and 175 GPa (2.3 and 1.75 Mbar) respectively, show that both oxides transform from their initial B1 (NaC1-type) structures at about 70 (* 10) GPa. CaO transforms to the B2 (CsC1-type) structure and FeO is inferred to do the same. Alternatively, FeO may undergo an electronic transition, but it probably does not disp...
متن کاملDensity Functional Study of FeO 2 , FeO + 2 , and FeO − 2 ALFONSO T . GARCÍA - SOSA , MIGUEL CASTRO
The lowest energy structures of FeO2 were determined by means of density functional theory techniques as implemented in the program DGauss 3.0.1. The calculations performed were of the all-electron type using two levels of theory, namely the local spin density approximation with the use of the Vosko–Wilk–Nusair (VWN) functional and the generalized gradient approximation (GGA) in the form of the...
متن کاملReaction between MnO-SiO2-FeO Inclusion and Steel Matrix Deoxidized by Si and Mn at Different Heat Treatment Temperatures
In order to clarify the effect of heat-treatment temperature on the reaction between solid steel and inclusions, in this study, the reaction between Fe-Mn-Si alloy and MnO-SiO2-FeO oxide during heat-treatment at 1373 K, 1473 K and 1573 K were investigated using diffusion couple method, respectively. The results indicate that the width of the particle-precipitated zone (PPZ) and the Mndepleted z...
متن کاملMelting Behaviour of Model Lherzolite in the System CaO–MgO–Al2O3–SiO2–FeO at 0·7–2·8 GPa
Fe–Mg exchange is the most important solid solution involved in for Fe–Mg exchange between the coexisting crystalline phases and melt, KdFe–Mg, show a relatively simple and predictable behaviour partial melting of spinel lherzolite, and the system CaO– MgO–Al2O3–SiO2–FeO (CMASF) is ideally suited to explore with pressure and temperature: the coefficients for olivine and spinel do not show signi...
متن کاملVibrationally resolved photofragment spectroscopy of FeO
We report the first vibrationally resolved spectroscopic study of FeO. We observe the 0←0 and 1←0 bands of a S←X S transition at 28 648.7 and 29 311 cm. Under slightly modified source conditions the 1←1 transition is observed at 28 473 cm. In addition to establishing an upper limit D0 (Fe1–O!<342.7 kJ/mol, our results give the first experimental measurements of the vibrational frequencies in bo...
