The precipitation of Fe₂O₃ from ferric chloride solution was invesgated in autoclave experiments. The minimum temperature to form Fe₂O₃ in the absence of Fe₂O₃ seed is 125℃. But in the presence of Fe₂O₃ seed, Fe₂O₃ is precipitated at temperatures as low as 100℃. The amount of iron precipitated and the concentration of co-generated HCI increase as the initial concentration of ferric chloride increase from 0.025 to 0.3M Fe₂O₃. Futher increases in the FeCl₃ concentration have a negligible effect on the quantity of Fe₂O₃ precipitated or on the concentration of HCI generated. Increasing initial HCI concentrations, however, sharply reduce the amount of Fe₂O₃.
