Abstract:

The solubility of WO3 in NaCl-KCl-NaF-WO3 molten salt system was measured by isothermal saturation method. The results show that in the molten salt system the solubility of WO3 increased with the increase of temperature from 700 °C to 820 °C, and the relationship between solubility and temperature is approximately linear. As shown in the XRD pattern, there are NaCl, KCl, NaF, WO3, Na5W3O9F5, Na3WO3F3 and NaWO3F in the molten salt, so the dissolution of WO3 is the result of both physical dissolution and chemical dissolution.
