Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines einteiligen, multinären Metalloxidpulvers, das zur Herstellung von Hochtemperatur-Supraleitern geeignet ist. Hierzu wir ein Gemisch der entsprechenden Metallsalze und/oder Metalloxide und/oder Metalle im erforderlichen stöchiometrischen Verhältnis in einen Pulsationsreaktor mit einer pulsierenden, aus einer flammenlosen Verbrennung resultierenden Gasströmung eingebracht und teilweise oder vollständig zum multinären Metalloxid umgesetzt.
