Abstract

Systematic studies have been made of the grain growth and density of sintered ZnO-based systems containing one or more additive oxides of the type $Nb_2O_5$, $Bi_2O_3$, $Sb_2O_3$, $CoO$, $Cr_2O_3$, $MnO_2$, $NiO$ and $Al_2O_3$. These samples were characterized using such techniques as scanning electron microscopy, X-ray diffraction and electron probe microanalysis. The influence of the nature and amount of additive oxides and sintering temperature is discussed in relation to microstructure, density and the phases present.
