In the present study, the thermodynamic properties of vanadium oxide in the CaO-Al2O3-VOx-SiO2 slag at 1873 K were investigated by equilibrating the slag with liquid Cu under C-CO equilibrium condition. The distribution ratios of V between the slag and liquid Cu were evaluated with respect to the slag composition. The distribution ratio showed a decreasing tendency with increasing Al2O3 concentration and an increasing tendency with increasing slag basicity.

摘要

In the present study, the thermodynamic properties of vanadium oxide in the CaO-Al2O3-VOx-SiO2 slag at 1873 K were investigated by equilibrating the slag with liquid Cu under C-CO equilibrium condition. The distribution ratios of V between the slag and liquid Cu were evaluated with respect to the slag composition. The distribution ratio showed a decreasing tendency with increasing Al2O3 concentration and an increasing tendency with increasing slag basicity.
