Аннотация: The phase, dispersive, and morphological features of an aluminum oxide powder produced by explosive synthesis are examined experimentally. It is shown that the particle-size distribution has three distinct maxima, which are due to different combustion regimes. The relationship between the sizes and morphology of the starting powderПоказать полностьюand the product is determined. Considerable attention is given to a study of the ultrafine fraction of the product powder. The ultrafine particles are shown to have a regular spherical shape, and sinters are not revealed. Besides spherical particles, the synthesized powder contains faceted crystals. X-ray phase analysis of the ultrafine fraction of the synthesized powders shows that this fraction consists only of the metastable phases of the oxide - the delta- or oxynitride modifications. The delta -modification differs from that described in the literature.
