Abstract This paper mainly discussed the basic principle and criterion of thermodynamics, and how to judge change direction and limit with the Gibbs free energy judgment. And the thermodynamic properties were studied in detail in the synthesis process of Fe/Fe3O4nanomagnetic materials. It can be concluded that Fe2+ ions can be used as starting materials to synthesize Fe/Fe3O4 magnetic materials by disproportionation reaction.
