Patent

CA 2314649

The present invention relates to a process for producing oxidic nanocrystals, the process comprising the following steps: a) Introducing host lattice ions as metalorganic complexes or volatile inorganic compounds into at least a first vaporizer, b) Converting the complexes or compounds into the gas phase and c) Transporting the resultant gas phase, with the aid of one or more carrier gases and/or carrier gas mixtures, into at least one heating zone of at least one reactor, and supplying one or more reaction gases and/or reaction gas mixtures, and d) Breaking down the complexes or compounds in the heating zone of the reactor at a pressure of between 1 - 1000 mbar, the oxidic nanocrystals being formed immediately, and e) Collecting the oxidic nanocrystals at at least one adsorption trap. The invention also relates to an apparatus for producing oxidic nanocrystals.
