Abstract:
The purpose of this work was to carry out an x-ray diffraction investigation of the formation of solid solutions and nonstoichiometric aluminum-magnesium spinels obtained from magnesium-modified aluminum hydroxides of various nature upon thermal treatment in the 823-1473 K temperature range. The influence of the nature of the original hydroxide, the concentration of the modifying additions, and the thermal-treatment conditions were studied. The results of the analysis of the x-ray diffraction patterns of magnesium-promoted aluminum oxide conducted show that the observed changes are best explained on the basis of the 'hydroxide-oxide' model of aluminum oxide. According to this model, the structure of the low-temperature solid solutions and nonstoichiometric spinels is characterized by a significant concentration of defects in the cationic (due to the filling of interstitial positions) and anionic (due to the presence of OH groups) sublattices.
