| Abstract: |
| Different compositions of Pr-Nd-Ce alloys were prepared by molten salt electrolysis in lithium fluoride-praseodymium neodymium fluoride-cerium fluoride system. 500 A scale electrolytic cell was used as a power source, and cerium oxide and praseodymium neodymium oxide were used as raw materials. Effects of electrolyte composition, temperature (980~1 060 ℃) and feed rate on electrolysis process were studied. The results show that electrolyte composition is the key to control stability of metal composition. However, temperature has little effect on metal composition. A low temperature or slow feed rate will bring increase of electrolyte liquid level. |
