Thermodynamic properties of rare?earth alloys by electrochemical emf measurements

Thermodynamic properties of Nd–Bi and Nd–Sn alloys were determined via electromotive force (emf) measurements at 725–1075 K. The emf an alloy mole fraction xNd = 0.20 conducted using a solid CaF2–NdF3 electrolyte relative to pure Nd(s). values from the verified in separate experiments molten LiCl–KCl–NdCl3 where Nd(s) was electrodeposited. (xNd 0.20) exhibited two?phase behavior with peritectic reaction (L + NdBi NdBi2) 926 K differential scanning calorimetry. employed as stable reference electrode for 0.15–0.40) 0.10) alloys. these reproducible during thermal cycles over 50 h used calculate thermodynamic properties, including partial molar Gibbs energy, entropy, enthalpy.
