| Abstract: |
| Density and surface tension of LiF-YF3-Y2O3 system are important factors in electrochemical preparation of yttrium alloy. Density and surface tension of LiF-YF3 and LiF-YF3-Y2O3 molten salt were measured by Archimedes and Detachment method with different concentrations and temperature (1 173—1 373 K). The results show that density and surface tension of LiF-YF3 molten salt linear drops with increase of temperature, but rise with increase of YF3 concentration. Density and surface tension of LiF-YF3-Y2O3(0—5%) molten salt rise firstly with increase of mass content of Y2O3, and drop with increase of Y2O3 mass content when Y2O3 mass content exceeds 2%. The empirical equations of molten salts are obtained by fitting quadratic equation, and changeable rule of density and surface tension are determined. |
