Аннотация: An explosive method for producing ultrafine alpha-Al2O3 is developed and optimal synthesis parameters are determined. Particles of ultrafine alpha-Al2O3 have a spherical shape and are separated from one another. The size distribution is log-normal (number-averaged size 70 nm and variance 1.9). Special features of phase transitions Показать полностьюin ultrafine aluminum oxide under shock-wave action are studied. Results of x-ray phase analysis suggest stabilization of the new high-pressure phase delta'-Al2O3 with a face-centered cubic lattice with a parameter a = 8.53 Angstrom.
