Effect of Na<sub>2</sub>WO<sub>4</sub> Content on the Crystallization Temperature of NaCl-KCl-Na<sub>2</sub>WO<sub>4</sub> Molten Salt System

The Liquidus Temperature of Molten Salt Nacl-Kcl-Na 2 WO 4 System was Measured by Differential Thermal Analysis. the Results Show that, in the Molten Salt System, when XNa2WO4≤0.7 Eutectic Temperature is 555 °C and a Phase Transition Temperature is 512.8 °C, Eutectic Composition Become XNaCl= 0.35, XKCl= 0.35, XNa2WO4= 0.3; when XNa2WO4>0.7, Eutectic Temperature and a Phase Transition Temperature are Respectively 613 °C and 574.4 °C, Eutectic Composition Become XNaCl= 0.1, XKCl= 0.1, XNa2WO4= 0.8.
