Abstract
Pore–boundary separation in ZnO and 99.95ZnO·0.05Bi2O3 (in mol%) specimens during sintering at 1200°C was investigated. In pure ZnO specimens, pores were attached to the grain boundaries and disappeared during the final stage of sintering. In the Bi2O3‐doped specimens, on the other hand, many pores were separated from the boundaries and trapped inside the grains. Observation using transmission electron microscopy showed that a thin layer of Bi2O3‐rich phase existed at the boundaries in the Bi2O3‐doped specimens. The pore separation in 99.95ZnO·0.05Bi2O3 specimens was explained in terms of the dihedral angle change and the high mobility of a liquid film boundary.
