ATOMIZATION OF NANOPOWDERS FOR ADSORPTION OF TOXIC SUBSTANCES

An experimental investigation of the dispersity and the specifi c surface of the particles of a pseudoboehmite nanopowder atomized by different methods for the purpose of formation of an aerosol has been carried out. It is shown that, as a result of the atomization of this power, the specifi c surface of its particles decreases and that this decrease is smaller in the case were the atomization is performed by the shock-wave method. The results of measurement of the dispersity of the particles of the pseudoboehmite powder in the process of its atomization and the further evolution of the aerosol cloud are presented. Photographs of aerosol particles have been obtained with the use of a scanning electron microscope
