· J. Am. Ceram. Soc.; (United States)
Magnetite and hercynite are candidate materials for electrodes in coal-fired MHD electric power generators. The cation distribution between tetrahedral and octahedral sites in the spinel crystal can be calculated from site-preference energies and used as an alternate method of determining some thermodynamic properties, including the Gibbs energy of mixing. 28 refs.
