摘要
Tetragonal zirconia polycrystal doped with 1.5 wt% CoO and 1.5 wt% Al2O3 showed large and faceted CoAl2O4 spinel grains existing in clusters and large monoclinic zirconia grains. Major stages of microstructural evolution during sintering included (1) formation of spinel as a result of preferred segregation of CoO to Al2O3 phase, (2) exudation of liquid phase to grain junctions among faceted spinel grains and zirconia grains, and (3) growth of spinel grains and the zirconia grains adjacent to the spinel phase.
