Zirconia jẹ ohun elo ti o ni agbara ẹrọ giga ati lile lile fifọ ni iwọn otutu yara. zirconia (ZrO2) wa ni afikun pẹlu 3mol% Y2O3 iduroṣinṣin zirconia (PSZ). Nitori iwọn ila opin patiku ti ohun elo PSZ jẹ kekere, o le ṣe ilọsiwaju pẹlu pipe to gaju, ati ohun elo rẹ ni awọn ẹya ẹrọ ṣiṣe deede gẹgẹbi awọn apẹrẹ ti n pọ si. Ni afikun, tun le ṣee lo fun awọn irinṣẹ ile-iṣẹ, awọn ẹya asopọ opiti ati awọn ohun elo fifun pa. Agbara fifọ giga ti PSZ le ṣee lo lati ṣe awọn orisun omi pataki, ati pe o tun jẹ lilo pupọ ni awọn ọbẹ seramiki ile, slicer ati awọn ẹya miiran.
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.
