摘要
稀土草酸盐中直接加氢氟酸置换生成氟化稀土 ,选择加入120%理论量的氢氟酸有较高的转化率和回收率。置换后草酸溶液循环使用 ,降低了成本。
The RE fluoride can be prepared directly from oxalate by adding hydrofluoric acid . The ratio of transformation and recovery is high if the hydrofluoric acid is added by 120% theoretical amounts. The oxalic acid solution can be re-used through displacement for reducing the cost.
