| Abstract: |
| Primary crystallization temperature of NaCl-KCl-NaF-Fe3O4 molten salt system was studied by differential thermal analysis. Effect of content of Fe3O4 and NaF on liquidus temperature of NaCl-KCl-NaF-Fe3O4 molten salt system was investigated. XRD and thermodynamic analysis of molten salt were carried out. The results show that Fe3O4 is physically dissolved in molten salt system. In XNaCl︰XKCl︰XNaF=3︰3︰4, when XFe3O4﹤30%, liquidus temperature of the system drops with increase of Fe3O4 content. Liquidus temperature of NaCl-KCl-NaF-Fe3O4 molten salt system rises with increase of NaF molar content. |
