Elemental Distributions Between Spinel and Liquid Phases in Vanadium-Bearing Slags at High Temperatures.

Herein the elemental distributions (V₂O₃, Cr₂O₃, Al₂O₃, and MgO) between spinel and liquid phases were identified in vanadium-bearing slags at 1200 °C to 1600 °C. The methodology includes melting, quenching and EPMA. We found upon increasing temperatures, V₂O₃ concentration in spinel decreased while that in liquid phase increased; and more CaO induced the transfer of V₂O₃ from spinel to liquid phase. This study provided important clues to target adjust elemental distributions among key phases in vanadium-bearing slags. [ABSTRACT FROM AUTHOR]
