ZnO varistors from intensively milled powders
(Elsevier B.V., 2007-01-01)
Two ways of application of intensive milling in ZnO varistors processing were compared. First was intensive milling of mixture of previously prepared constituent phases. In this case, intensive milling was applied only to ...
Recent research developments in SnO2-based varistors
(Elsevier B.V., 2005-03-15)
This paper discusses some advances in research conducted on SnO2-based electroceramics. The addition of different dopants, as well as several thermal treatments in oxidizing and inert atmospheres, were found to influence ...
Degradación y recuperación de varistores de ZnO
(2006-09-01)
In the present work it was studied the main aspect that influences on degradation and physical-chemical properties at grain-boundary region of metal oxide varistors and its consequences on microstructure and nonohmic ...

Controlling the breakdown electric field in SnO2 based varistors by the insertion of SnO2 nanobelts
(2017-04-01)
Semiconducting metal oxides have many practical applications, including varistors. Varistors based on SnO2 exhibit both high nonlinear coefficients and high breakdown electric fields. In this work we present a facile means ...
