摘要
采用化学共沉淀法制备La(OH)3和Nd(OH)3微粉,研究了反应物浓度、氨水浓度、滴定速度以及加入分散剂对制备La(OH)3微粉和Nd(OH)3微粉粒度的影响,初步确定了制备D50≤1μm的La(OH)3微粉和Nd(OH)3微粉的最佳工艺条件。
The properties of La(OH)_3 and Nd(OH)_3 micropowders prepared by coprecipitation were studied. During precipitation the state of agglomeration can be controlled by high polymer additives instead of alcohol.The optimal preparing condition of micropowders (D_(50)≤1μm) were proposed.
