Estimating the term…
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.
A process for producing inorganic fullerene-like (IF) metal chalcogenide nanoparticles, the process comprising:
TiS2 nanoparticles having fullerene-like structure and a diameter size of between 10-300 nm.
An apparatus for preparing IF nanostructures, the apparatus comprising:
Inorganic fullerene-like (IF) metal chalcogenide nanoparticles having a plurality of molecular layers and characterized in that the number of said molecular layers exceeds 40.
A product comprising a plurality of inorganic fullerene-like (IF) metal chalcogenide nanoparticles, a substantial portion of which having a number of molecular layers exceeding 40.
