Zirconia waa shay leh awood farsamo oo sarreeya iyo adkaanta jabka heerkulka qolka. Zirconia (ZrO2) waxaa lagu daraa 3mol%Y2O3 qayb ka mid ah zirconia deggan (PSZ). Sababtoo ah dhexroorka walxaha PSZ waa yar yahay, waxaa lagu farsameyn karaa si sax ah, iyo codsigeeda qaybaha mashiinnada saxda ah sida caaryada ayaa sii kordhaya. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa qalabka warshadaha, qaybaha isku xirka indhaha iyo qalabka wax lagu burburiyo. Adkeysiga sare ee jabka ee PSZ waxaa loo isticmaali karaa in la sameeyo ilo gaar ah, waxaana sidoo kale si weyn loogu isticmaalaa mindiyaha dhoobada gudaha, jarjaran iyo qaybo kale.
Astaamaha ugu muhiimsan ee qaybaha dhoobada zirconia:
1. Xiro aad u fiican oo iska caabin ah, oo aad uga sarreeya 276 jeer ka badan birta aan lahayn
2. Cufnaanta ka sarreysa inta badan dhoobada farsamada, in ka badan 6 g/cm3
3. Adag oo sarreeya, in ka badan 1300 MPa oo loogu talagalay Vicker
4. U adkeysan kara heerkulka sare ilaa 2400°
5. Kulaylka kuleylka hooseeya, in ka yar 3 W/mk heerkulka qolka
6. Isku-dhafka la midka ah ee ballaadhinta kulaylka sida birta aan la karin
7. adkaanta jabka aan caadiga ahayn waxay gaartaa ilaa 8 Mpa m1/2
8. Kiimiko la'aan, caabbinta gabowga, oo aan miridhku weligii dhicin
9. U adkaysiga biraha dhalaaliyay sababtoo ah meel dhalaalaysa oo aan caadi ahayn.
