摘要：

In this paper, nanometer-sized magnetic pigment Fe3O4 was prepared by co-precipitation method. The forming mechanism of Fe3O4 was investigated and the relationship between the content of Fe2+ and the magnetism of Fe3O4 was also studied. The color character of Fe3O4 was measured and nanometer-sized magnetic pigments Fe3O4 were characterized by XRD, IR, TEM and VSM. The results show that the sample is well-proportioned in distribution and small in size (about 10 nm). The shape of the sample particles is spherical. Munsell marking is N1.28/. The specific saturation magnetization intensity is maximal, i.e. 84.03 A m(2) kg(-1), when the proportion of Fe2+ to Fe3+ is 1.6:2. On the other hand, it has certain superparamagnetic properties.
