Аннотация: A method is proposed to study the sequence of phase transitions in powdered materials under a shock-wave action. It is shown that the "aluminum hydroxide-alumina" system has the following sequence of phase transformations under a shock-wave action: bayerite --> boehmite --> gamma-Al2O3 --> alpha-Al2O3. It is found that there are noПоказать полностьюtransitional high-temperature modifications of alumina. A method is developed for obtaining a submicron alumina powder, which allows obtaining materials with a controlled phase composition, including a thermodynamically stable a-modification of Al2O3. The specific features of the morphological structure and the phase and structural characteristics of powders after a shock-wave action are considered.
