摘要：
The structure of finely dispersed iron powders obtained by electrodeposition with oleic acid as a stabilizer and isophytol as an adsorptive modifier has been studied by X-ray photoelectron, gamma resonance and infrared spectroscopies. The finely dispersed iron powders were shown to be microcrystals whose alpha-iron "core" is covered by a magnetite oxide film 30-70 angstrom thick, which in its turn is covered by a two-layer condensed stabilizing coating. The latter consists of 1:1 iron carboxylate complexes having a chelate bidentate configuration.
