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 gas flow, which results from a flameless combustion, and is partially or completely converted into multinary metal oxide.
La présente invention concerne un procédé de production d'une poudre d'oxyde métallique multicomposant, à particules fines, qui convient à la production de supraconducteurs résistants aux hautes températures. Selon ce procédé, un mélange des sels métalliques et/ou des oxydes métalliques et/ou des métaux correspondants, présentant le rapport stoechiométrique nécessaire, est introduit dans un réacteur pulsé avec un courant gazeux pulsé, résultant d'une combustion sans flamme, puis est complètement ou partiellement transformé en oxyde métallique multicomposant.
