EMF measurements on liquid Na-Hg alloys and their thermodynamic properties

The EMF of the liquid Na-Hg system has been measured as a function of temperature and from these measurements we have obtained the thermodynamic quantities of mixing: Delta G, Delta S and Delta H. The temperature variations of Delta H were observed. The authors then estimated Delta C_p, the additional specific heat by alloying. In connection with this, the fluctuations in the long-wavelength limit S_cc(0), S_NN(0), S_Nc(0) and the partial structure factors a_ij(0) of Faber-Ziman type were estimated. They also estimated the local ordering parameter from these partial structure factors.
