Abstract
Magnesium aluminate spinel is obtained in the MgO-Al2O3-Al system using the method of self-propagating high-temperature synthesis. The leading SHS reaction is the oxidation of aluminum in an oxidizing environment. The composition and structure of spinel were studied by X-ray diffraction (DRON-UM-1), infrared spectroscopy (Nicolet 5700) and scanning electron microscopy (Philips SEM 515). The mineralizer NaCl used in the amount of 1 wt.% increases the conversion depth during SHS. Initial components are ground in a M3 planetary mill for 60 s results to obtain MgAl2O4 that does not contain impurities of initial oxides. The grain size of magnesium aluminate spinel obtained is ≤1 microns.
