Specificities of the Controlled Synthesis of Nanostructured Oxides in the Dust Flame

The methods of controlled synthesis of nanostructures of zinc and aluminum oxides by combustion methods are studied. The results of the experimental studies on the control of disperse characteristics of aluminum oxide nanoparticles by introduction the atoms of low-ionized additives into the system are presented. It is shown that the producing the nanostructures of aluminum and zinc oxides by the same method - gas-disperse synthesis - has fundamental differences. This difference is due to the peculiarity of a zinc burning process - a gaseous reaction of zinc vapor and oxygen is impossible. Therefore, the zinc nanostructures grow quite differently and for their producing another methods of controlling their size and shape are required.
