For measuring the effective gas diffusivities through the reduced phase of iron oxide pellet, an unreacted core model is generally used. However, as this diffusivity is obtained based on the specific hypotheses characteristic to the model, it is just a parameter. On the other hand, as the diffusivity obtained by the Wicke-Kallenbach method can measure the diffusivity directly, the obtained value is intrinsic. In the present study, the diffusivities obtained by use of both methods were compared for the respective reduced phases (iron, wustite, magnetite) of iron oxide pellets and the inconsistencies in those values were examined.effective gas diffusivitiesiron oxide pelletunreacted core modelWicke-Kallenbach method
