Abstract
Dispersity, structure, phase composition, and thermal stability of powders prepared by the mechanical activation of iron in a heptane containing vinyltriethoxysilane (VTES) are studied by the X-ray diffraction analysis and Mössbauer, Auger-, and X-ray photoelectron spectroscopy. It is shown that the presence of VTES in the grinding medium makes it possible to prepare powders with the mean particle size on the order of 1 μm and to form a nanocomposite comprising a mixture of α-Fe and Fe3C phases separated by interlayers of a third phase (iron silicate and/or silicon dioxide). The prepared nanocomposite is thermally stable up toT = 800°C.
