Zirconia wani abu ne da ke da ƙarfin injina da ƙarfin karyewa a zafin jiki. An ƙara zirconia (ZrO2) tare da 3mol% Y2O3 barga zirconia (PSZ). Domin barbashi diamita na PSZ abu ne karami, shi za a iya sarrafa tare da high madaidaici, da kuma aikace-aikace a daidai machining sassa kamar molds ne fadada. Bugu da ƙari, kuma za a iya amfani da kayan aikin masana'antu, sassa masu haɗin kai da murkushe matsakaicin kayan aiki. Za'a iya amfani da tauri mai ƙarfi na PSZ don yin maɓuɓɓugan ruwa na musamman, kuma ana amfani da shi sosai a cikin wuƙaƙen yumbu na gida, slicer da sauran sassa.
Babban halaye na sassan yumbura na zirconia:
1. Kyakkyawan juriya na lalacewa, mafi girma sau 276 fiye da bakin karfe
2. Mafi girma fiye da yawancin yumbu na fasaha, fiye da 6 g / cm3
3. Babban taurin, sama da 1300 MPa don Vicker
4. Zai iya jure yanayin zafi mai girma har zuwa 2400 °
5. Low thermal conductivity, kasa da 3 W / mk a dakin da zazzabi
6. Similar coefficient na thermal fadada kamar bakin karfe
7. Ƙarya na musamman ya kai har zuwa 8 Mpa m1/2
8. Chemical inertness, tsufa juriya, kuma ba tsatsa har abada
9. Juriya ga narkakkar karafa saboda wani wuri na narkewa mai ban mamaki.
