摘要：

The mechanism of formation of magnetite from an aqueous alkaline slurry of Fe(OH)2 is shown to involve the sequence dissolution-oxidation-nucleation on Fe(OH)2-growth of Fe3O4. The dependence of the size and shape of the particles on experimental conditions is discussed. Barium (II) is not incorporated in the oxidative formation of magnetite because of the conflicting solid state chemistry of Ba(II) and Fe(II).
