The effect of a combination of water-soluble magnesium and aluminum salts on the physicochemical properties of the obtained aluminomagnesium spinel was studied. It was shown that the formation of aluminomagnesium spinel occurs in the range of 800…1050 ? from synthesized xerogels based on different ratios of magnesium and aluminum chlorides and nitrates. It was found that the crystalline structure of the spinel is completely formed during heat treatment of xerogels from synthesized pairs of AlCl3 + MgCl2 salts at 900 °C and holding for 60 minutes, while they have smaller crystallite sizes compared to other heat-treated xerogels. It was revealed that a higher temperature of 1050 ? is required to obtain spinel from xerogels synthesized on the basis of pairs of Al(NO3)3 + MgCl2 and Al(NO3)3 + Mg(NO3)2 salts.
