Abstract: Mechanical activation of a mixture of silicon oxide and aluminum is studied by methods of infrared spectroscopy, differential thermal analysis, and x-ray diffraction. If a SiO$_2$/Al mechanocomposite is used as a precursor, then a Si/Al$_2$O$_3$ composite with a small grain size and a uniform distribution of the components can be obtained by the method of self-propagating high-temperature synthesis.

Keywords: mechanical activation, mechanocomposites, silicon oxide.
