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.
