| 摘 要： | 依据碳酸氢铵沉淀氯化钕时pH的变化,提出了沉淀、结晶化反应方程式,考察了加料速度、加料比、陈化时间对碳酸钕结晶过程的影响,确定了快速沉淀晶型碳酸钕的工艺条件。所得产品纯度大于99%,氯根质量分数低于1.0×10-4,粒度均匀,并可快速结晶。

| Abstract: | Based on changing of pH during settling neodymium chloride with ammonium bicarbonate solution, the settling and crystal equations were put forward. The effects of adding rate of ammonium bicarbonate solution, m(NH_4HCO_3)/m(NdCl_3) ,aging time of solution on neodymium carbonate crystallization were examined. The process conditions about rapidly settling and crystal of neodymium carbonate ware determined. |
