Microstructure–property relationship in textured ZnO-based varistors
Acta Materialia, 2010 The relationship between microstructure texturing and electrical characteristics of a ZnO-based varistor system was investigated in comparison with a varistor system having the same chemical composition but conventional microstructure. Highly textured ZnO-based varistors were produced via the templated grain growth (TGG) technique.

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Abstract Microstructure homogeneity and grain size reduction are needed to ensure the current uniformity and reliability required in metal oxide varistors for DC circuit breakers. Cold sintering (CS)–a low‐temperature digestive liquid and high‐pressure densification process–has previously shown reduced grain growth, but it is not clear how the lower ...

Effect of sintering temperature and heat treatment on electrical properties of indium oxide based ceramics [PDF]
, 2008 Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

High Voltage, Volume 10, Issue 3, Page 673-679, June 2025.Abstract This study focuses on the distribution of high‐resistance media (pores and spinels) within ZnO $\text{ZnO}$ varistors and explores the mechanical and electrical failure mechanisms of varistors under different pulse actions. Micro‐CT technology revealed that the proportion of high‐resistance media in the edge area is much higher than in the ...
