以碳酸氢铵作沉淀剂，从氯化钕料液中沉淀钕，经陈化结晶制备碳酸钕。
Crystalline neodymium carbonate was prepared by aging amorphous neodymium carbonate, which was formed by the reaction of neodymium chloride and ammonium bicarbonate, at elevated temperature.
结果表明：随着结晶陈化温度的提高，结晶碳酸钕中氧化钕含量升高，而增大碳酸氢铵加入量则使氧化钕含量降低。
It was found that the neodymium oxide content in neodymium carbonate increased with adding temperature increasing and decreased with the feed molar ratio increasing.
在不同的工艺条件下能生产出晶型型貌不同的少钕碳酸稀土。
Less neodymium rare earth carbonate with different crystalline feature can be produced.
结果表明，碳酸镨钕中60%的铝可以去除。
The results show that aluminum of 60% in praseodymium-neodymium...
