摘要：

Formation of solid solutions in magnesia-alumina systems has been studied. It has been shown that depending on the method of introduction of magnesium and the temperature of heat treatment, formation of three types of solid solutions with the structure of gamma-alumina is possible; the anionic, the anionic-cationic and the cationic type. The mechanical strength of the obtained samples of spherical alumina depends on the method of modification; the strongest samples are produced if magnesium is added to aluminium hydroxide with subsequent calcination at 820 K.
