Dilute solutions of ferrous sulfate, sulfuric acid, hydrochloric acid, nitric acid and acetic acid in which iron powders are dispersed have been oxidized at below 80°C by blowing air into them. The resulting precipitates have been examined by means of X-ray diffraction, chemical analysis and optical and electron microscopy. When the iron powder is well dispersed, γ-FeOOH is formed with or without α-FeOOH, α-Fe<SUB>2</SUB>O<SUB>3</SUB>, or Fe<SUB>3</SUB>O<SUB>4</SUB>. The mode of formation depends on such factors as particle size, amount of iron powder, kind of anion present and temperature. Particle size greatly influences the formation of γ-FeOOH in the sulfate system, but not in the other systems.
