Effect of NaWO3F Content on the Liquidus Temperature of NaCl-KCl-NaWO3F Molten Salt System

The liquidus temperature of molten salt NaCl-KCl-NaWO3F system was measured by differential thermal analysis. The results show that in the molten salt system when :=1:1, XNaWO3F <0.5 the liquidus temperature decreased with the increase of NaWO3F content; when :=1:1, XNaWO3F>0.5 the liquidus temperature increased with the increase of NaWO3F content; the eutectic temperature is 615.9 °C, the eutectic composition is =0.25, =0.25, XNaWO3F=0.5.
