采用氨络合沉淀法制备了Ni(OH) 2 微粒。基于Ni(OH) 2 的结构特征 ,考察了阴离子、氨浓度、反应陈化时间对Ni(OH) 2 的结构控制规律 ,并用负离子配位多面体生长基元理论对此进行解释 ,认为通过改变反应体系物理化学条件来改变有关生长基元及其维度、连接方式是控制粉体结构的有效途径
Ni (OH) 2 particles were prepared by ammonia complex precipitation method. Based on the structural characteristics of Ni (OH) 2, the structure control laws of Ni (OH) 2 anion and ammonia concentration and reaction aging time were investigated and explained by using the principle of anion coordination polyhedron growth unit. System physicochemical conditions to change the growth of the cell and its dimensions, the connection is an effective way to control the structure of the powder
