| Abstract: | The magnetic properties of Fe3O4 ultrafine particles prepared by chemical coprecipitation are closely related to the mixing process of precipitators, the concentrations of the solution and the molar ratios of Fe2+/Fe3+/OH-, etc. We have improved the method of the chemical coprecipitation and found that there are an obvious increase in the magnetic properties and crystal degree and an obvious decrease in the size of Fe3O4 ultrafine particles. |
