| 摘 要： | 采用化学共沉淀法制备纳米磁性Fe3O4粒子。选用NH3.H2O作为沉淀剂,加入到Fe2+和Fe3+的混合盐溶液中,制得了纳米磁性Fe3O4粒子。考察了影响产物粒径的一些实验因素。通过X-Ray谱图证实了产物结构特征,平均粒径在37 nm左右,平均晶粒度只有28 nm左右的均分散。

| Abstract: | Nanometer magnetite Fe3O4 particles were prepared by chemical co-precipitation,NH3·H2O was chosen as precipitating agent and added to the mixed aqueous solution containing ferric and ferrous ions to produce nanometer Fe3O4 particles.Some influence factors on the size were investigated.The phase structure of the particle was measured by XRD test,and the average size was about 28 nm. |
