Abstract :
Systematic researched have been made of the grain growth and density of sintered ZnO-based systems containing one or more additive oxides of the type Bi2O3, MnO2, and CoO. These samples were characterized using such techniques as scanning electron microscopy. The influence of the nature and amount of additive oxides and sintering temperature at 950 to 1350°C is discussed in relation to microstructure, breakdown voltage and the density present.
