| Abstract: | Electromotive force cells have been used to determine the Gibbs free energies, enthalpies, and entropies of formation for Th2Fe17, ThFe5, Th2Fe7, ThFe3, and Th7Fe3 over the temperature range 928 to 1164 K. Solid CaF2 was used as the electrolyte. Comparisons of Th-Fe, Th-Co, and Th-Ni thermodynamic data show patterns which correlate with crystallographic and magnetic behavior. Some inferences have been drawn about the bonding interactions within the phases in these alloy systems. formerly Graduate Students, Department of Metallurgy, Iowa State University, Ames, Iowa 50010, |
