Microstructure and Nonohmic Properties of SnO2-Ta2O5-ZnO System Doped with ZrO2 [PDF]
The microstructure and nonohmic properties of SnO2-Ta2O5-ZnO varistor system doped with different amounts of ZrO2 (0–2.0 mol%) were investigated. The proposed samples were sintered at 1400°C for 2 h with conventional ceramic processing method.

Micro-Degradation Characteristics and Mechanism of ZnO Varistors under Multi-Pulse Lightning Strike
In view of the problem that ZnO varistors are often subjected to thermal breakdown and deterioration due to lightning strikes in low-voltage power distribution systems, this article used a 8/20 µs multi-pulse surge current with a pulse time interval of ...

Advances in the synthesis of ZnO nanomaterials for varistor devices [PDF]
ZnO based varistors are widely used for overvoltage protection in many electrical and electronic circuits, at voltages ranging from a few to over a million volts. By careful control of the microstructure, through nano-structuring by chemical routes, it should be possible to produce varistors with high breakdown voltage (Vc), as this is proportional to ...
