Abstract

The invention relates to a method for producing a one-part, multinary metal oxide power which is suitable for producing high-temperature superconductors. To this end, a mixture of the corresponding metal salts and/or metal oxides and/or metals in the requisite stoichiometric ratio is introduced into a pulsed reactor with a pulsed gas flow resulting from flameless combustion and is partially or completely converted into the multinary metal oxide.
