Abstract：
 The present invention discloses preparation process of nanometer ferromagnetic oxide particle. Metal ion solution is reacted in the mixed system comprising alkali metal hydroxide, fatty acid and organic polar solvent to obtain the nanometer ferromagnetic oxide particle. The present invention prepares nanometer ferromagnetic oxide particle inside the mixed solvent system comprising fatty acid and polar solvent and with soluble metal salt and alkali metal hydroxide as main material. The preparation process of the present invention is simple, safe, low in cost and suitable for preparing several kinds of nanometer noble metal particle, and has less environmental pollution, and the prepared nanometer ferromagnetic oxide particle may be applied in biology, medicine, catalysis, analysis and other fields.
