抄録

The mixed powder of ZrO₂(3Y) and Al₂O₃ was ground by a bead milling method. The particle sizes of ZrO₂(3Y) and Al₂O₃ were reduced to 10 nm and 18 nm by milling for 377 hours, respectively. Open pores in the specimen sintered at 1300°C were diminished to less than 0.1% of total volume for fine mixed powder milled for 422 hr, while open pores in the specimen sintered at the same conditions using mixed powder milled for 1 hr showed more than 17%. Therefore, it was concluded that the reduction of particle size mentioned above greatly enhanced the sinterability of the mixed powder. The relative density reached more than 99.7% of theoretical density when the pre-sintered bodies free from open pores were HIP'ed at temperatures from 1300°C to 1500°C under Ar gas pressure of 196 MPa. The bending strength of the HIP'ed specimen was 1520 MPa although that of pre-sintered specimen was 800 MPa.
