Non-uniform ageing behavior of individual grain boundaries in ZnO varistor ceramics

In this paper, the ageing characteristics of individual grain boundaries in ZnO varistor ceramics were directly measured for the first time, which were carried out based on the microcontact technique in combination with accelerated AC voltage ageing tests. The current–voltage ( I– V) characteristics...
