Beschreibung
Zusammenfassung:	The invention relates to a method for producing a fine-particle, multinary metal oxide powder that is suitable for producing high-temperature superconductors. To this end, a mixture consisting of corresponding metallic salts and/or metal oxides and/or metals provided in the required stoichiometric ratio is introduced into a pulsed reactor with a pulsating ga s flow, which results from a flameless combustion, and is partially or completely converted into multinary metal oxide.
