The thermodynamic equilibria between chromium oxide, chromium carbide, and a CO-CO2 mixture was calculated for various conditions. Experimental results on the rate of the Cr2O3 conversion to chromium carbide in CO-CO2 mixtures at 1200°C are reported. The conversion rate was low and was strongly dependent on the carbon activity.
