Microstructure control to reduce leakage current of medium and high voltage ceramic varistors based on doped ZnO [PDF]

, 2014
International audienceThe leakage current and the non-linearity coefficient (α) are crucial parameters in varistors. This work, deals with the optimization of the electrical characteristics of medium and high voltage varistors based on the ZnO–Bi2O3 ...

Electrical Properties of ZnO-Bi₂O₃ Metal Oxide Heterojunction — A Clue of a Role of Intergranular Layers in ZnO Varistors

, 1981
Zinc Oxide (ZnO) Ceramics-Bismuth Oxide (Bi2O3) Metal Oxide thin film heterojunction made by sputtering technique showed a highly non-Ohmic property. The voltage-current characteristics and the dielectric properties showed dependence on Bi2O3 metal oxide

Full-Lifecycle Deterioration Characteristics and Remaining Life Prediction of ZnO Varistors Based on PSO-SVR and iForest

Energies
To address three core deficiencies of the existing research on ZnO varistors (incomplete full-lifecycle datasets, insufficient characterization robustness due to the lack of multi-parameter complementarity, and disconnected remaining life prediction and ...

Using percolation to design ZnO composites with hBN modified grain boundaries to obtain varistor-like behavior

Open Ceramics
Conventional varistors rely on the formation of a Double Schottky Barrier within the intergranular region of ZnO via acceptor doping and a Bi2O3 phase. This work has been able to yield varistor-like behavior via cold sintered ZnO composites by placing 2D

Screen-printed varistors: New strategy for high non-linear coefficient

, 2007
Screen-printed thick film varistors (TFV) based on ZnO powder were developed with the aim to protect IGBT power transistors against overvoltages. The electrical characteristic of TFV was shown to depend on the electrode composition.
