  • Process and apparatus for producing inorganic fullerene-like nanoparticles
    Patent number: 7959891
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.

  • Process and apparatus for producing inorganic fullerene-like nanoparticles
    Patent number: 7641886
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor (INi) selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber (12) towards a reaction zone to interact with a flow of at least one chalcogen material (IN2) in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core and also exhibiting excellent tribological behavior. The present invention further provides an apparatus for preparing various IF nanostructures.
