| Abstract: | The primary cell reported in this paper was composed of saturated calomel electrode and platinum electrode, used as reference and indicator electrode respectively. Through controlling the electromotive force of the primary cell, the ratio of Fe 3+ and Fe 2+ concentration in the mixed solution could be fixed at 2. After adding this mixed solution to excessive ammonia solution, Fe 3O 4 formed and was characterized by XRD and IR methods. |
