Ferrites/Ferrates, etc

[budullewraagh]

recently i've been considering making ferrates and ferrites, etc from Fe2O3.

can anybody tell me how the following reactions sound?

 

Fe2O3(s)+KOH(l) -->K2Fe2O5 (Fe oxidized from +3 to +4)

upon addition of water, i believe that it would break to form 2KHFeO3

 

Fe2O3+NaOCl(aq)+KOH-->K2FeO4

^scratch that, as it would yield HClO which would decompose the ferrate

 

i have heard of this method:

Fe2O3+KNO3-->K2FeO4

but also, i believe it would work with chlorates/perchlorates as the oxidizing agents.

Fe2O3+2KClO3+10HCl -->K2FeO4

^may yield some deranged chlorine oxides though:\

 

Fe2O3+Na2O2(l)+KOH(l)-->K2Fe2O5

anyone here have an idea of the feasibility of these reactions?

obviously not, your the smartest chem here at the moment, they sound good to me briefly checking in chem encylos, wheres Wolfson?

I think the Perchlorates is the best method to go for.

With the sodium peroxide method, you'll need to be VERY careful as the heating of the peroxide to a liquid form could easily catalyze it's decomposition which would be quite bad.

yeah, i have reservations on the chlorate/perchlorate on because of certain formation of chlorine oxides. the sodium peroxide method scares me, quite frankly. the nitrate method and the hypochlorite/hydroxide method don't produce great yields, unfortunately.
