摘要： The invention relates to the production of fine-particle metal oxide powders containing alkali metals, said powders containing at least one alkali metal and at least one other metal from the group of transition metals, the other main group metals, lanthanides and actinides. Precursor compounds of said constituents are introduced into a pulsed reactor with a gas flow resulting from a flameless combustion, in a solid form or in the form of a solution or a suspension, where they are partially or fully reacted to form the desired multi-constituent metal oxide powder.
