Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanospheres, comprising: (a) feeding a metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into a reacting chamber towards a reacting zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reacting zone being such enabling the immediate formation of spherical nucleation seeds of the product; (b) controllably varying the flow of said metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into said reacting chamber thereby controlling the amount, morphology and size of the so-produced nanospheres, to obtain substantially non-hollow fullerene-like metal calcogenide nanospheres in solid form. The present invention further provides novel IF metal chalcogenides with substantially non-hollow, spherical shape, and having excellent tribological behaviour. The present invention also provides an apparatus for preparing various IF nanostructures.

Abstract: A method for the preparation of nanoparticles of metal oxides containing inserted metal particles and to metal-intercalated and/or metal-encaged “inorganic fullerene-like” (hereinafter IF) structures of metal chalcogenides obtained therefrom is provided, which comprises heating a metal I material with water vapor or electron beam evaporation of said metal I material with water or another suitable solvent, in the presence of a metal II salt, and recovering the metal II-doped metal I oxide, or proceeding to subsequent sulfidization, yielding bulk quantities of metal II-intercalated or metal II-encaged IF structures of the metal I chalcogenide. The metal II salt is preferably an alkaline, alkaline earth or transition metal salt, most preferably an alkali chloride. The intercalated and/or encaged IF structures are usable as lubricants. They also form stable suspensions, e.g. in alcohol, and electrophoretic deposition from said suspensions yields thin films of the intercalated IF materials, which have a range of potential applications.
