摘要
采用化学共沉淀法制备了纳米Fe3O4粉体材料。用溶液吸附法、透射电镜、X射线衍射仪和古埃磁天平法对添加柠檬酸根前后的纳米Fe3O4粉体材料的结构及性能进行了表征和分析。结果表明:添加柠檬酸根制备的纳米Fe3O4粉体材料的比表面积为1.499,晶粒粒径为8nm,磁化率为11.6534,颗粒度小,分散性好,磁性能更高。
Nano-Fe3O4 powder materials were prepared by using chemical co-precipitation method.The structure and properties of nano-Fe3O4 powder with citrate and without citrate were characterized and analyzed by solution adsorption,transmission electron microscopy,X-ray diffraction and Gouy magnetic balance method.The results reveal that：the specific surface area of nano-Fe3O4 powder which prepared by adding citrate is 1.499,grain particle size is 8nm,magnetic susceptibility is 11.6534,smaller particle size,better dispersion and strong magnetic performance.
