| Abstract | 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 → γ-Al2O3 → α-Al2O3. It is found that there are no transitional 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 α-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. |
