Abstract

A comparative analysis of the methods and technologies used to produce nanopowders is performed. The fundamentals of both the traditional technology for chemically synthesizing inorganic nanocrystalline particles of metal oxides by the crystallization of precursors (amorphous metal hydroxides obtained by chemical coprecipitation from salts) and the most promising methods for producing nanopowders and materials on their basis (including the dispersion of monodisperse flows of liquids and solutions in an electrical field and a plasma technology that involves electrical arc recondensation of substances) are considered. The studies performed at the State Research Institute of Organoelemental Compound Chemistry and Technology (SRIOCCT) are taken as examples to describe methods for the recondensation of coarse powders of silicon, silicon carbide, and aluminum oxide in low-temperature argon plasma. The most efficient regimes of the process, difficulties, and unresolved problems are analyzed. Results of the physicochemical investigations and tests of the synthesized pilot samples are described.
