PREPARAZIONE DI PARTICELLE ULTRA FINI DA MICROEMULSIONI DI ACQUA IN OLIO

Process for preparing ultrafine inorganic particles of size lower than 50 nm, preferably lower than 10, with narrow size distribution, of metals, oxides, sulphides, carbonates by starting from microemulsions of water in a fluorinated oil, preferably a perfluoropolyether oil, containing metal ions in...

Summary:Process for preparing ultrafine inorganic particles of size lower than 50 nm, preferably lower than 10, with narrow size distribution, of metals, oxides, sulphides, carbonates by starting from microemulsions of water in a fluorinated oil, preferably a perfluoropolyether oil, containing metal ions in the aqueous phase and by reacting them with a reactant which is gaseous, or vapour, in the reaction conditions, for obtaining the above indicated compounds.
