The preparation of finely divided, alkali metal-containing metal oxide powders which contain at least one alkali metal and at least one further metal from the group consisting of the transition metals, the remaining main group metals, the lanthanides and actinides is described. Precursor compounds of these components are introduced in solid form or in the form of a solution or a suspension into a pulsation reactor having a gas flow resulting from a flameless combustion and partly or completely converted into the desired multicomponent metal oxide powder. |
