Awọn abuda akọkọ ti awọn ẹya seramiki zirconia:
1. O tayọ resistance resistance, Elo ti o ga 276 igba ju irin alagbara, irin
2. Iwọn iwuwo ti o ga julọ ju awọn ohun elo imọ-ẹrọ, ju 6 g / cm3 lọ
3. Lile giga, lori 1300 MPa fun Vicker
4. Le withstand ti o ga awọn iwọn otutu soke si 2400 °
5. Imudara iwọn otutu kekere, kere ju 3 W / mk ni iwọn otutu yara
6. Iru olùsọdipúpọ ti igbona imugboroosi bi irin alagbara, irin
7. Iyatọ ṣẹ egungun toughness Gigun soke si 8 Mpa m1/2
8. Kemikali inertness, ti ogbo resistance, ati ki o ko ipata lailai
9. Resistance to didà awọn irin nitori ohun extraordinary yo ojuami.
