Thermal Conductivity of FLiNaK in a Molten State
Although the thermal conductivity of molten salt mixtures is of interest for many potential technological applications, precise values are often hard to obtain.

| description | Although the thermal conductivity of molten salt mixtures is of interest for many potential technological applications, precise values are often hard to obtain. In this study, the thermal diffusivity of FliNaK was studied in a molten state using the laser flash method and found to be very slightly dependent on temperature. The heat capacity of FliNaK was measured using the DSC method. There was a minor difference between our results and data from the literature. From calculations based on thermal diffusivity, density and heat capacity values, thermal conductivity was shown to decrease with temperature. |
