It was found that the neodymium oxide content in neodymiumcarbonate increased with adding temperature increasing and decreased with the feed molar ratio increasing.
Crystalline neodymiumcarbonate was prepared by aging amorphous neodymiumcarbonate, which was formed by the reaction of neodymium chloride and ammonium bicarbonate, at elevated temperature.
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。
