This study critically evaluated and predicted the condensed phases in a multicomponent chloride system, and proposed two innovative quaternary eutectic chlorides with low melting points. The experimental results were consistent with the theoretical predictions, indicating the potential of these new chlorides as candidates for thermal energy storage and transfer materials in solar power plants.
Molten chloride mixtures are of great scientific and technical interest for sensible heat storage in solar power generation. In this work, the condensed phases in a LiCl-NaCl-KCl-ZnCl2 multicomponent system were critically evaluated and predicted via literature review and simulations of LiCl-KCl and KCl-ZnCl2 systems. Two innovative LiCl-NaCl-KCl-ZnCl2 quaternary chloride systems with low melting points were proposed and developed on the basis of a thermodynamic design. The thermal-physical properties of these two eutectic compositions, including melting point, mixing enthalpy, specific heat capacity, density, thermal conductivity, and mass loss, were then experimentally determined. The experimental results were consistent with the theoretical predictions. The novel quaternary eutectic chlorides with excellent thermophysical properties developed herein are potential candidates for thermal energy storage and transfer materials in concentrating solar power plants.
