Abstract

In this study, ZnO was sintered with the addition of P₂O ₅-a liquid forming oxide, and the effects of the sintering temperature and P₂O₅ content on microstructure evolution were investigated. When sintering was conducted below 1100 °C the grain size was almost constant in the studied range, regardless of the P₂O ₅ content, and elongated/faceted grains with straight solid-liquid interfaces were observed. However, the grain size decreased as the amount of P₂O₅ increased, and rounded/spherical grains were observed when sintering was conducted at temperatures above 1100 °C. The observed changes in grain size and microstructural evolution are explained by the reaction and the diffusion controlled grain growth at low and high temperatures, respectively.
