Title: Processing and properties of ZnO-based varistors

Abstract

The objective of this work is to study the influence of sintering temperature and additive content on the electrical characteristics and microstructure of ZnO based varistors with Bi/sub 2/O/sub 3/ (always present), Sb/sub 2/O/sub 3/, Co/sub 3/O/sub 4/, MnO/sub 2/ and Cr/sub 2/O/sub 3/ as additive oxides. The influence of sintering temperature and additive content on the electrical characteristics of ZnO based varistors without Bi/sub 2/O/sub 3/, but with additives from the rare-earth oxide series such as Eu/sub 2/O/sub 3/, La/sub 2/O/sub 3/, Pr/sub 6/O/sub 11/ and Ho/sub 2/O/sub 3/, is also studied. Procedures and results are presented in detail.
