Abstract

Process for producing metal oxide powders by means of flame spray pyrolysis, in which an aerosol comprising a metal compound is introduced into a flame in a reactor and reacted therein, and the metal oxide powder obtained is separated from gaseous substances, whereina) the flame is formed by the ignition of an oxygen-containing gas (1) with a fuel gas,b) the aerosol is obtained by joint atomization of a solution containing a metal compound and an atomization gas by means of one or more nozzles andc) the ratio of the spray area to the cross-sectional reactor area is at least 0.2.
