Abstract

Abstract Translated from German Verfahren zur Herstellung eines Dielektrikums aus ferroelektrischer Keramik mit Perowskitstruktur der Grundformel ABO3, bei dem das Dielektrikum in reduzierender Atmosphäre gesintert und dieser Sinterkörper bei einer Temperatur im Bereich von 500 bis 900°C in einer N2-O2-Atmosphäre mit einem O2-Anteil entsprechend einem O2-Partialdruck zwischen 10<-><5> bar und 0,2 bar nachbehandelt wird. Process for producing a dielectric made of ferroelectric ceramic with a perovskite structure of the basic formula ABO3, in which the dielectric sinters in a reducing atmosphere and this sintered body at a temperature in the range from 500 to 900 ° C. in an N2-O2 atmosphere with an O2 content corresponding to one O2 partial pressure between 10 <-> <5> bar and 0.2 bar is aftertreated.
