From these model parameters, the optimised ternary phase diagram of the FeO – Fe2O3 –SiO2 (Fe – O – Si) system was back calculated. The database of the model parameters can be used in conjunction with computer software for Gibbs-free-energy minimisation in order to calculate all ...
Theoretical study of activation Fe–O bond of FeO + by CO in the gas phase The entire reaction mechanism for the gas phase CO–CO 2 conversion by FeO + is discussed by means of the density functional theory and the intrinsic react... YC Wang,DP Chen,ZY Geng,... - 《Journal of Mole...
Liquidus surface of FeO-Fe{sub}2O{sub}3-SiO{sub}2-CaO slags is an important parameter in various smelting and converting processes. It helps not only to optimize the slag chemistry of current processes and their fluxing strategies but also to determine the availability of new slags for more...

We identified this feature as the qAFMR of hematite (α-Fe2O3) [47]. From its amplitude (≈0.04 dB/K), compared to the amplitude measured in a 0.5-mm-thick single crystal hematite (≈30 dB/K), we can estimate that the amount of hematite impurity in our sample was about 0.2...
A part of the phase diagram of the system PbO-B 2O 3-Fe 2O 3-Y 2O 3 has been investigated. The system has been treated as the "ternary" system S-Fe 2O 3-Y ... HD Jonker - 《Journal of Crystal Growth》 被引量: 53发表: 1975年 Optical, photophysical and magnetic behavior of...
IT has already been reported1,2 that a stable compound having a chemical composition near TiO2.Fe2O3 can be produced by ultimate oxidation of the ilmenite-hmatite mineral series, xFeTiO3.(1-x)Fe2O3, or titanomagnetites, yFe2TiO4.(1-y)Fe3O4. Very little is known, however, about ...
