Abstract

The cation distribution in stoichiometric Fe3O4 was determined from thermopower measurements at 600° to 1500°C. The distribution varies from inverse at low temperature to random at ∼1450°C. The equilibrium constant for cation distribution can be expressed as In KCD=2770/T−1.61, indicating temperature‐independent enthalpy and nonconfigurational entropy terms of −23.0 and −13.4 J/mol‐K, respectively.
