Abstract By using an interferometric technique, the refractive index of some molten salt mixtures containing Cs+ ions was measured with high accuracy: (Li-Cs)NO3, (Na-Cs)NO3, (Ag-Cs)NO3, (Li-Cs)Cl, and also pure RbCl. The isotherms of molar refractivity show a small negative deviation from additivity in the (Li-Cs)NO3 and (Li-Cs)Cl systems and a positive deviation in the (Ag-Cs)NO3 mixture. A tentative attempt was made to relate the excess molar refractivities with the absorption bands of the ions.

The refractive index of molten NaCl, KCl, CdCl2, and PbCl2 and of the molten systems NaCl + CdCl2, NaCl + PbCl2, KCl + CdCl2, and KCl + PbCl2 has been measured over a range of temperature. From these results and published density data, molar refractivities have been calculated. The deviation of molar refractivity from the values calculated on the basis of additivity gives further evidence for the formation of complex ions in the KCl + CdCl2 and KCl + PbCl2 systems. In the NaCl + CdCl2 and NaCl + PbCl2 systems there is simple mixing without interaction.

An anomalous increase of the specific heat was experimentally observed in molten salt nanofluids using a differential scanning calorimeter. Binary carbonate molten salt mixtures were used as a base fluid, and the base salts were doped with graphite nanoparticles. Specific heat measurements of the nanofluids were performed to examine the effects of the composition of two salts consisting of the base fluid. In addition, the effect of the nanoparticle concentration was investigated as the concentration of the graphite nanoparticles was varied from 0.025 to 1.0 wt %. Moreover, the dispersion homogeneity of the nanoparticles was explored by increasing amount of surfactant in the synthesis process of the molten salt nanofluids. The results showed that the specific heat of the nanofluid was enhanced by more than 30% in the liquid phase and by more than 36% in the solid phase at a nanoparticle concentration of 1 wt %. It was also observed that the concentration and the dispersion homogeneity of nanoparticles favorably affected the specific heat enhancement of the molten salt nanofluids. The dispersion status of graphite nanoparticles into the salt mixtures was visualized via scanning electron microscopy. The experimental results were explained according to the nanoparticle-induced compressed liquid layer structure of the molten salts.

Abstract For additive binary molten salt mixtures the ionic mobilities, the interdiffusion mobility and the self diffusion mobilities are defined. Values of these mobilities are given for the system NaNO3+AgNO3 at 290 °C in dependence of the composition.
