| 摘 要： | 研究以FeSO4·7H2O和FeCl3·6H2O为原料，NH3·H2O作为沉淀剂，采用共沉淀法制备纳米Fe3O4颗粒，利用IR（红外光谱）、XRD（X射线衍射）等表征手段对割得的纳米颗粒进行了表征。结果表明：制备的纳米Fe3O4粒子粒径较细，且粒径分布较窄。据此找出制备纳米Fe3O4粒子的最佳实验条件为：铁盐溶液浓度为0．5mol／L，沉淀剂溶液浓度为0．2mol／L，Fe^2＋：Fe^3＋：OH^-=1．00：1．00：6．00，反应温度为30℃。制备纳米Fe3O4粒子粒径在10-20mm，且分散性较好；通过XRD谱图可以得出产物为具有立方晶系的纳米Fe3O4粒子。 |

| Abstract: | Small size and mono-disperse Fe3O4 nanoparticles were prepared by co-precipitation in which FeSO4-7H2O and FeC13-6H2O were used as raw materials and as precipitating agents. IR （IR）, XRD （X-ray diffraction）, and other means of the system were used to characterize the Fe3O4 nanoparticles. The results showed that the size of Fe3O4 nanoparticles was small and mono-disperse. At room temperature, the appropriate conditions on preparation of Fe3O4 nanoparticles were 0.5 mol/L FeCl3, 0.2 mol/L NH3·H2O and Fe2＋ ： Fe3＋ ： OH-=1.00 ： 1.00 ： 6.00 at 30℃. The size of Fe3O4 nanoparticles was 10～20 nm and the mono-dispersion was good. From XRD patterns, the Fe3O4 nanoparticles were face cubic crystal. |
