摘　　要：研究了草酸氨沉淀钴过程中NH4+浓度对产品的颗粒和形貌的影响。由于NH4+的作用使溶液的离子强度增加,粒子对体系中阴离子的吸附量增大,粒子的形貌随着溶液中NH4+浓度的增加变粗短,最终形成方形粒子,松装密度增大。The effect of concentration of NH4^＋ on the particle size and morphology of the product is studied. NH4^＋ can enhance the ionic strength of solution and the adsorptive capacity of anion. And the particle gets thicker and shorter with the increasing of the NH4^＋ concentration. Therefore, the particle turn into quadratic form and its loose density increases.
