Iron ferrate synthesis
« on: January 28, 2006, 05:55:54 PM »
Hi,
I'm new and I have a question about iron ferrate (FeFeO4) synthesis. So how to make it ? Maybe something like that :2guns: :
2KNO3 + Fe --> K2FeO4 + 2NO  ???
and next:
K2FeO4 + FeSO4 --> FeFeO4 + K2SO4  ???

In what environment should I make this synthesis and maybe with some catalysts or inhibitors?

Greets 4 all  ;)

Ferrate anion is a powerful oxidant, hence Fe(II)FeO4  probably cannot exists.

So you might then think of Fe(III) ferrate Fe2(FeO4)3 = Fe5O12. But Fe(III) is strongly acidic, and [FeO4]2- is stable only in alkaline conditions. FeO2 containing Fe(IV) rather than being Fe(II) ferrate (VI) may be possible, but for Fe(IV) so far only mixed oxides such as BaFeO3 are known, and various complexes with organic molecules.
