Аннотация: The paper considers a physical model for the explosive synthesis of ultrafine aluminum oxide, which assumes that in a compression wave the starting material is divided into layers with different states of aggregation and grain-size compositions. The relationship between the synthesis conditions and the properties of the product is studied. It is shown that the yield of the ultrafine fraction in the synthesized powder depends on the conditions of metal oxidation during dispersion, shock-wave parameters, and the velocity of dispersion of the starting material into the gas medium of the explosion chamber. Experimental data are used to determine the layer sizes and the constants characterizing the possibility of vapor-phase oxidation of aluminum during explosive synthesis. In the coordinates corresponding to the process parameters (yield of the ultrafine fraction and the masses of the explosive and the starting metal), a synthesis surface is constructed and optimum parameters for production of ultrafine material are determined.
