| Abstract: | In this paper, the ultra-fine particles of Fe3O4 coated with a single layer of molecular oleic acid were prepared by the neutralizing co-precipitation solution-adsorption process. The particle size, shape and structure of Fe3O4·nOA wore primarily studied by electron microscopy, infrared spectroscopy, DTA-TG, X-ray diffraction, etc. Some of the methods of calculation and measurement of the particle size and quantity of oleic acid in Fe3O4·nOA were provided by testing and supposition. |
