Kinetics deformation of current-voltage characteristics of the varistor oxide structures due to overcharging of the localized states

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014
Prolonged exposure of zinc oxide varistors to the electrical load leads to current-voltage characteristics (CVC) deformation, which is associated with a change in the height and width of the intergranular barriers, which are the main structural element ...

Solid state compatibility in the ZnO-rich region of ZnO-Bi₂O₃-Sb₂O₃ and ZnO-Bi₂O₃-Sb₂O₅ systems

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The obtaining of ZnO-Bi2O3-Sb2O3 (ZBS) based varistor thick films with high non-linear properties is constrained by the bismuth loss by vaporization that takes place during the sintering step of these ceramics, a process which is yet more critical in the
