摘要
The effect of pressure has been studied on the oxidation state of Fe(IV) in SrFeO289 and of Fe(VI) in BaFeO4-x. Fe(IV) reduces to Fe(III) with increasing pressure, and Fe(VI) reduces to Fe(IV) with perhaps some production of Fe (III). The first process is reversible but the second is not. In neither case does the simple relationship between concentration and pressure found for the reversible reduction of Fe(III) to Fe(II) hold.
