The process of obtaining of a dispersed product based on metallic iron, containing a protective carbosiloxane film on the surface, has been investigated and implemented. The structure and composition of the metal product are characterized by modern physical methods, including X-ray phase and X-ray fluorescence analysis, XPS spectroscopy. The influence of the synthesis mechanism, the role of the metal-silicon chemical interaction in the surface layer on the water-repellent and anticorrosion properties of the obtained samples is considered. It was found that the heat resistance of the samples in air and their hydrophobicity, depending on the type of the reduced metal, increase in the order: nickel - copper - iron. It was shown that highly hydrophobic iron-based samples can be obtained by reduction from iron (II) oxide and Olenegorsk superconcentrate. The prospects of the synthesized powders and the method of their preparation for the creation of superhydrophobic materials are shown. A method for obtaining a metal product has been theoretically and experimentally substantiated, where the formation of a metal structure and its protection from an aggressive environment are carried out within a given volume on the same technological unit with a flow-through reactor.
