摘要

To improve the properties of zirconia-toughened-alumina (ZTA) ceramics, a technique which involves hydrolysis of Zr(OC3H7)4 in an Al2O3 slurry to form an Al2O3 powder with uniformly distributed ZrO2 is described. The addition of TiO2 within its solubility limit enhanced sinterability of the powder. A relative density of 98% can be obtained by firing at 1500°C for 2 h. The presence of TiO2 promotes the grain growth of Al2O3 and ZrO2, and contributes to the retention of tetragonal ZrO2 in the sintered body.
