【Abstract】 The preparation of nano-Fe₃O₄ powder has been studied. The effect of the reaction （condition） such as the reaction time, the concentration of the reactants, the reaction temperature and the （concentration） of the precipitant on the yield has been obtained. The product was characterized by （infrared） spectroscopy and X-ray diffraction. The results are as follows: the optimum temperature is （35 ℃） and the optimum concentration of the precipitant is 0.01 mol·L^-1.更多还原
