Abstract
The oxidation behaviours of iron powders, ca. 100 μm in diameter, in 5-50 m NaOH, 5-40 m KOH and 5-40 m LiOH solutions at 373-573 K were investigated in the absence and presence of oxygen, where m is molality. The oxidation of iron proceeded noticeably above 423 K to form Fe3O4, α-Fe2O3, α-NaFeO2, γ-Fe2O3, LixFe3-xO4 and α-LiFeO2 depending on the reaction conditions. The rate of oxidation in LiOH solutions was much slower than those in NaOH and KOH solutions.
