Thermal properties of fluoride mixtures near the melting point

Year: 2025

Type: article

Abstract: The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain temperature range. Thermal diffusivity of eutectic FLiNaK and NaF-KF mixtures was found to drop sharply at the temperatures of 30–50 ° below the melting point. These values correspond to the overcooling interval. Thermal conductivity was calculated using the thermal diffusivity heat capacity and density data. Thermal diffusivity of the FliNaK-NdF3 mixture decreases slowly in the phase transition temperature range.
