Abstract
The sintering behavior of an Al2O3 compact containing uniformly disper sed Al2O3 platelets has been investigated. The results reveal a signif icant decrease in the sintering rate as well as the formation of voids and cracklike defects in the presence of nonsinterable platelets. The addition of a small amount (2 vol%) of tetragonal-ZrO2 particles enha nces the sintering rate, increases end-point density (similar to 99.5% of theoretical density) and prevents formation of sintering defects.
