Reduction equilibria of multi-component calcium ferrite with CO-CO₂ gas mixture

Reduction equilibria of multi-component calcium ferrite contained in self-fluxing sinter with a CO-CO₂ gas mixture have been investigated by the electrochemical method. Using a solid electrolyte as well as the thermogravimetric method, the results are different from those previously obtained on the reduction equilibria of binary calcium ferrite. They are the same as those obtained on the reduction sequence of pure iron oxides.
