Depending on the process, the type of iron can influence process stability. During fluidized bed reduction, the formation of iron whiskers should be avoided due to sticking phenomena that can result in defluidization. Dense iron precipitates can affect the reduction rate negatively because they prevent reducing gas penetration into the particle.
