“…An et al . 27 also employed the laser flash technique, but they also observed heat losses attributed to a heat leak to the side of the cell. Furthermore, their two measurements also show an increasing thermal conductivity with temperature, indicating the strong influence of unaccounted for heat loss.…”

The available experimental data for the thermal conductivity of 13 inorganic molten salts have been critically examined with the intention of establishing thermal conductivity reference correlations. All experimental data have been categorized into primary and secondary data according to the quality of measurement specified by a series of criteria. Standard reference correlations are proposed for the following molten salts (with estimated uncertainties at the 95 % confidence level given in parentheses): LiNO3 (7 %), NaNO3 (7 %), KNO3 (15 %), NaBr (15 %), KBr (15 %), RbBr (15 %), LiCl (17 %), NaCl (20 %), KCl (17 %), RbCl (17%), CsCl (10 %), NaI (17 %), and RbI (20 %).

“…Thermal transport at high temperatures is a significant process for many applications [1], such as concentrated solar power (CSP) plants [2,3], thermal energy storage [4], and thermal barrier coatings for gas-turbine engines [5]. There are several established techniques for high temperature thermal conductivity measurement, such as the laser flash analysis (LFA) [6,7], transient hot-wire (THW) [8], hot-disk transient plane-source (TPS) [9,10], 3ω method [11][12][13], as well as the pump-probe time or frequency domain thermoreflectance (TDTR/FDTR) techniques [14][15][16][17], etc. However, there are still limitations of these techniques under certain circumstances, for example, on samples with rough surfaces and at high temperature.…”

“…The measurement was repeated with a new LNC-MO disk to confirm the reproducibility. The measured thermal diffusivity (α) was converted into thermal conductivity (λ) through the expression λ = αρC p [32]. A push rod dilatometer was used to determine the density (ρ) and a separate DSC measurement (Table S1) was performed to attain the heat capacity (C p ).…”

Recently, there has been a noticeable increase in the applications of composite mixtures containing molten salt and solid oxide for thermal energy conversion and storage systems. This highlights that thermal conductivity of the composites are central for the purpose of designing and devising processes. Measuring the thermal conductivity of molten samples at elevated temperatures remains challenging. In this study, the possibility to use heat flux differential scanning calorimetry (DSC) to measure the thermal conductivity of molten samples at elevated temperatures is reported for the first time. The thermal conductivity of composite mixtures containing eutectic (Li,Na)2CO3 with and without selected solid oxides at ~675 °C was determined by using the proposed DSC approach. This mixture is a candidate for high temperature waste heat conversion to electric energy. In the DSC measurement program, steps with repeated thermal cycles between 410 and 515 °C were included to limit the effect of the interface thermal contact resistance. The determined values 0.826 ± 0.001, and 0.077 ± 0.004 W m−1K−1 for the carbonate mixtures with and without solid MgO were found to match the reliable analysis at similar conditions.
