Among all the properties required for the design of the next generation ofPCM (density, heat capacity, thermal expansion, latent energy, volume changeupon melting, corrosion rate, etc.) the thermal transport properties are by farthe least known, especially for molten salt mixtures and solid solutions. Wepresent in this paper a theoretical framework for accurate predictions ofthermal conductivity of multicomponent salt-based PCM, from 273.15 K up toabove melting temperature. The solid phase is considered as a microstructurewith its proper temperature dependent parameters: phase volume fraction, grainsize distribution, porosity, etc. As case studies, five new potential PCMs forCSP applications are considered. Their thermal conductivity is estimated as afunction of temperature, from room temperature to 200 K above their meltingpoint. The predictive capability of the proposed framework is discussed basedon a comparison with available experimental data. The effect of equilibrium andnon-equilibrium microstructural parameters (i.e. phase fraction, phasecomposition, average grain size, inter-grain, and intra-grain porosity) on theeffective thermal conductivity of the solid states of the promising chloridePCMs is discussed. Lastly, recommendations for the design of next generationsof PCM materials are suggested in order to improve their thermal transportproperties.
