This paper deals with a major effect of ytterbium on microstructure, electrical and dielectric properties, and aging characteristics of ZVM (ZnO–V2O5–Mn3O4) system. With the amount of the ytterbium increased, the average grain size decreased from 7.2 to 5.9 µm, whereas the density of the sintered pellets increased from 5.39 to 5.55 g/cm3. The breakdown field increased from 922 to 3774 V/cm with the...
