Abstract

Effect of sintering atmosphere on maximum energy capability of Pr-doped ZnO varistor has been studied. Distribution of electrical property and microstructure in ZnO varistor has been obtained with sliced sample. It is shown that donor density and interface states density increased with N₂-Air sintering, and there is the close relationship between distribution of electrical property of grain boundary and maximum energy capability. Segregation of Pr and Cr at triple point was different with sintering atmosphere. The composition of segregation phase was Pr-rich PrCrO₃, Pr₄O₇ and Pr₂O₃ with N₂-Air sintering.
