| Abstract: |
| In order to obtain high quality Gd-Fe intermediate alloy, the initial crystal temperature, density, viscosity and dissolution behavior of gadolinium oxide in the electrolyte of LiF-GdF3 were studied. It was found that the initial crystal temperature decreased with the increase of LiF content, which was caused by the complexation of GdF3 and LiF to generate LiGdF4 heat release. The electrolyte viscosity decreases with the increase of LiF content. At the specified temperature, the electrolyte density increases with the increase of GdF3 content. When the electrolyte is matched, the density decreases with the increase of temperature. The prepared Gd-Fe intermediate alloy products are mainly composed of Gd and GdFe2, and the composition is uniform. |
