Abstract
Annealing experiments in nitrogen, oxygen, and reducing atmospheres are made on mechanically damaged ZnO ceramics. The annealing effect is monitored by means of the sample CL emission. Deformation induced damage appears to be unstable at temperatures above 1040 K indepently of the annealing atmosphere. The role played by reducing and oxidizing treatments on the CL changes in damaged areas is discussed on the basis of different charge states of copper.
Der Einflus des Anlassens in N2, O2 und in reduzierenden Atmospharen auf verformte ZnO-Keramik-Proben wird mittels Kathodolumineszenz untersucht. Die von der Verformung erzeugte Defektstruktur ist instabil beim Anlassen uber 1040 K, unabhangig von der Behandlungsatmosphare. Der Effekt von oxydierenden und reduzierenden Behandlungen auf die KL von geschadigten Probengebieten wird auf der Basis der Zustande von Kupferverunreinigungen diskutiert.
