Study of Solubility of WO₃ in the NaCl-KCl-NaF-WO₃ Molten Salt

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 when the temperature rise to 700 °C the saturation time of the WO₃ dissolution time is 6 hours. When the temperature rise to 730 °C from 700 °C the saturation time of the WO₃ dissolution time needs 80 minutes. As shown in the XRD pattern, there are NaCl, KCl, NaF, WO₃, Na₅W₃O₉F₅, Na₃WO₃F₃ and NaWO₃F in the molten salt.
