Lower oxygen content in prereduced chromiteiron ore pellets means preferential reduction of trivalent irons to divalent irons in sesquioxide solid solution (Fe, Cr, Al) 2 O 3 rather than that in chromite spinel (Fe 2+, Mg)[Cr, Al, Fe 3+] 2 O 4, and consequently causes greater mass loss of oxygen. It can also prove more sesquioxide solid solution forms in chromiteiron ore pellets.
