In order to examine the effect of cold isostatic pressing (CIP) in powder compacting process on sintering of Y-TZP with 3 mol% Y2O3, the press formed powders by uniaxial loading were isostatically compressed under water pressures from 25 MPa to 500 MPa and fired at temperatures from 1300°C to 1500°C in air. The densification was achieved at lower temperatures with increasing the magnitude of pressure in CIP treatment. The relative density reached over 99% of theoretical when the powders were sintered at 1300°C after CIP treatment.
