共沉淀酸蚀法制备CoFe_2O_4磁性液体及其中的微粒粒径分布

Coprecipitation-acid Method to Prepare Magnetic Fluid CoFe_2O_4 and It's Particle Size Distribution

采用共沉淀法制备CoFe2 O4超细微粒 ,用酸蚀法配制CoFe2 O4磁性液体 .采用TEM照片分析 ,发现共沉淀法制备的CoFe2 O4超细微粒粒径分布为双纵数分布 。

We employ the method of coprecipitation to prepare CoFe\-2O\-4 ultra fine particle, and acid process to prepare magnetic fluid CoFe\-2O\-4. By using TEM photography to test the distribution of particle size, findings are that the distribution of particle size of the CoFe\-2O\-4 ultra fine particle prepared from the method of coprecipitation appears to be double mode distribution, whereas the distribution of particle size in the magnetic fluid appears to be LOG normal.
