Summary

Electrical conductivity, thermoelectric power and viscosity measurements were carried out in the wide temperature range for the liquid alloys NaF–LiF–LaF3 and NaF–LiF–NdF3, which can serve as blanket components for the molten salt reactors. The electrical conductivity and the thermoelectric power were measured by a contact method in accordance with the 4-point scheme. The dynamic viscosity was measured by oscillating-cup method. It was found that the melt viscosity significantly depends on the chemical composition and varies 1,5 – 2 times during transition from the eutectic concentration to the peritectic one. The same shift significantly alters the temperature dependence of the thermoelectric power. However, the temperature dependence of the electrical conductivity of the samples with lanthanum and neodymium remain practically unchanged.
