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 SiO2/Al mechanocomposite is used as a precursor, then a Si/Al2O3 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.
