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.

机械损伤ZnO陶瓷的退火效应
合并氮气氧气和减少大气层是机械震动ZnO ceramics的试验方法合并效应是samcro的地址未经高温压制住大气层,原属一属1040克它设定了减少和氧化处理不同的二分之一利用双筒火箭筒对N2、O2和缩水的zo陶瓷样本的影响进行分析。歪曲的错误结构由治好法产生,原属不稳定,由治疗方案必不可少。oxydierenden和reduzierenden治疗方法的效果的升geschadigten Probengebieten的基础上由Kupferverunreinigungen .讨论
