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.
