The Enthalpy Of Formation

The enthalpy change on cooling molten and solid salts and their mixtures from temperatures as high as 850� down to 26.9� has been measured by means of a Bunsen-type fusion calorimeter. The enthalpy of formation of solid mixtures has also been measured using a water solution calorimeter. From the combined results, heats of mixing have been determined for the molten salt systems investigated. In each system, with the exception of CdCl2 + PbCl2, the process of mixing is exothermic and the relative magnitude of the results can be explained by the formation of complex ions in the systems CdC12 +NaCl, CdCl2 +KCl, PbCl2 +KCl, and CdI2 +KI. Complex ions have not been detected in the other systems.

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.

The electromotive forces of galvanic cells for the formation of PbBr2 in the molten binary salt systems, PbBr2-KBr, PbBr2,-RbBr and PbBr2-CsBr, have been measured. Activities, activity coefficients and partial molar free energies have been calculated for each component of the three systems. Integral free energies of mixing have also been calculated. Various models of mixing of molten salts have been applied to the results. The systems contain complex ions, probably mixtures of PbBr42-, PbBr64- with some PbBr3-.

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.
