Effect of WO₃ Content on the Liquidus Temperature of NaCl-KCl-NaF-WO₃ Molten Salt System

Abstract

The liquidus temperature of molten salt NaCl-KCl-NaF-WO3 system was measured by differential thermal analysis. The results show that in the molten salt system when 0.1379 eutectic temperature is 616.5 °C, eutectic composition is =0.3846, =0.3846, =0.1923, =0.0385; when >0.1379, eutectic temperature is 628.9 °C, eutectic composition is = 0.3390, = 0.3390, =0.1695, = 0.1525.
