Abstract

Electromotive force cells have been used to determine the Gibbs free energies, entropies, and enthalpies of phase formation for Th2Ni17, ThNi5, ThNi2, ThNi, and Th7Ni3. Solid CaF2 was em ployed as the electrolyte, and it has previously been shown that CaF2 is an ionic conductor over the temperature range of measurements, 841° to 1141°K. The experimental results can be correlated with the atomic coordinations in the crystal structures of these five Th-Ni intermediate phases.
