Abstract
The effect of addition nanoAl2O3 on sintering behavior and mechanical property of ZrO2 was studied. It was shown that the addition of nanoAl2O3 with the Al2O3 content from 0.5mol% to 2.0mol% in ZrO2 ceramics could accelerate the sintering of ZrO2 and increase the flexural strength and fracture toughness of ZrO2. ZrO2 added with 1.0mol% nanoAl2O3 has the maximum in strength of 650MPa and toughness of 15MPa·m1/2 sintered at 1450°C. Compared with undoped ZrO2 being sintered at 1500°C, the strength and toughness was improved by 12% and 18%, respectively.
