Abstract The rate constant of oxygen transfer reaction between the molten iron
oxide and CO2 gas on the surface of liquid slag was measured by
the isotope exchange method. Also, according to the electrochemical
mechanism in the reaction process, the effect of P2$O5 additive
was discussed and a new model was established. From this model, due to
participating the electron competition while volatilizing from slag,
P2$O5 decreases the oxygen transfer rate. The results of
analyzing and fitting to the experimental data have indicated that
this new model is available to explain the effect of P2O5,
and supported the view which there exits an electrochemical mechanism
in this process.
