An apparatus for producing oxidic nanocrystals from metal organic compounds or volatile inorganic compounds comprises an apparatus which includes a first vaporizer which is connected to a first carrier gas stream to produce a first reactant gas stream, a second vaporizer is connected to a second carrier gas stream to produce a second reactant gas stream the first and second reactant gas streams are connected to a first feed line and flow heated reactor wherein the reactants are heated and reacted to provide oxidic nanocrystals which are unagglomerated having a mean particle size of up to 20 nanometers.

Apparatus for producing oxidic nanocrystals

The present invention relates to oxidic nanocrystals and a process and apparatus for producing oxidic nanocrystals from metalorganic compounds or volatile inorganic compounds. In particular, the process is suitable for oxidic or oxysulfidic nanocrystals, particularly based on the elements Y, Gd, Mg, Ca, Ba and Al. The nanocrystals preferably have a mean initial particle size of 1 to 20 nm.

Process and apparatus for producing oxidic nanocrystals

The electrode component according to the invention is produced by means of the metal powder injection molding method. As a result, complex shapes can be realized for the electrode.
