摘要： 本文提出了一种共沉淀——溶液吸附法制备单分子层油酸包覆Fe3O4超微粒子的方法,并采用透射电镜比表面测定,差热和热重,X光衍射和红外光谱分析等对其颗粒的形状、大小和结构作了初步探讨.提出了颗粒度和油酸吸附量的简易估算和测定方法.

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.
