Production of metal nanopowders: Al, Cu, Fe, Ni, MgAl, Ag, Ti; oxides: Al2O3, TiO2, Fe2O3, γ-Fe2O3, CuO, CuO+Cu2O, (MgAl)2O3; complex oxides: YSZ, ScSZ, GdC, SDC, etc.; various mixtures of oxides has been worked out. All powders are poorly aggregated; the shape of the particles is close to spherical. Particle size dBET for metals 40-100 nm, for oxides 5-200 nm.
A method for obtaining weakly aggregated al, Mg Al powders to obtain their homogeneous mixtures with ceramic powders is proposed and worked out.
Plants for the production of nanopowders of metals, alloys and their chemical compounds by EEW were created. The plants are automated and provide productivity up to 150 g/h for metals and up to 400 g/h for oxides.
