Abstract

The characteristics of varistors based on M.Matstuokas with one another ZnO powder (50nm, 100nm, 300nm) have been investigated. The optimum calcination and sintering temperature was also selected for each samples. Varieties of sintering conditions were found according to powder size. As the result of analysises on each operating voltages. We obtained the most high voltage in a sample with 50nm ZnO powder.
