ThenThe invention relates to a process for the preparation of monooxidesnof finely divided particles (P) of an average particle size betweenn10 nm to 50 μm,nin which a raw material dispersion (RD) or raw material emulsion (RE),nconsisting of a raw material mixture (RM) containing at least all componentsncontaining the solid particle (P) to be formed, and at least one thereofnimmiscible component (K), the raw material dispersion (RD)nor raw material emulsion (RE) in the hot gas stream (HGS) of a thermalnReactor (1) is introduced with pulsating combustion, whereinnthere the particles (P) are formed and then thenformed particles from the hot gas streamn(HGS) are separated. |
