Influence of processing parameters on microstructure and electrical properties of ZnO-based varistor ceramics

Discover Electronics
ZnO-based varistors are widely used in electrical equipment for surge protection. This research explores the influence of sintering parameters—such as sintering temperature, ramp rate and soaking time—on microstructure development and V-I characteristics

Desenvolvimento de varistores à base de SnO2 para aplicação em redes de alta tensão Development of SnO2-based varistors for high voltage application

Cerâmica, 2006
Varistores à base de SnO2 foram preparados pelo processo convencional de mistura de óxidos. As amostras foram sinterizadas a 1250 °C por 2 h. Os difratogramas obtidos por difração de raios X e as análises por microscopia eletrônica de varredura ...

Processing parameters for ZnO-based thick film varistors obtained by screen printing

Boletín de la Sociedad Española de Cerámica y Vidrio, 2006
Thick film varistors based on the ZnO-Bi2O3-Sb2O3 system have been prepared by screen printing on dense alumina substrates. Different processing parameters like the paste viscosity, burn out and sintering cycles, green and sintered thickness, have been ...

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
