摘要：

In this paper, magnetite nano-particals were rapidly prepared using a chemical reduction method. The effects of dispersant type and its dosage, calcining temperature and calcining time were studied by X-ray powder diffraction (XRD). The results present that the conditions to obtain the magnetite nano-particals with a perfect inverse spinel type structure are the dispersant type of PEG(6000), the dispersant dosage of 50 g/L, the calcining temperature of 700°C, the calcining time of 120 min. The VSM analysis demonstrate that the saturation magnetization of the magnetite nano-particals was 85 A·m2/kg, and the samples showed strong paramagnetism due to its coercivity tending to 0.
