Physical properties of liquid NaF–LiF–LaF3 and NaF–LiF–NdF3 eutectic alloys

► Molten NaF–LiF–LaF3 and NaF–LiF–NdF3 eutectics can be used in liquid salt reactors. ► A stepped dissociation exists well above melting in the both alloys. ► Anomalous properties behavior proves that a short-range order persists after melting. ► Transformation of structure spread to a wide temperat...

description ► Molten NaF–LiF–LaF3 and NaF–LiF–NdF3 eutectics can be used in liquid salt reactors. ► A stepped dissociation exists well above melting in the both alloys. ► Anomalous properties behavior proves that a short-range order persists after melting. ► Transformation of structure spread to a wide temperature range in the liquid phase. Electrical conductivity, thermoelectric power and viscosity measurements were carried out for the ionic liquid mixtures, formed after melting of the NaF–LiF–LaF3 and NaF–LiF–NdF3 eutectics in the wide temperature intervals above the melting points. It was found that temperature coefficient of the thermoelectric power of the both ionic mixtures changes a sign, at 948±5K in NaF–LiF–LaF3 and at 973±5K in NaF–LiF–NdF3. It was shown that temperature dependence of viscosity correlates with electrophysical data. The results can be used in choosing a blanket for the liquid salt reactor.
