I-Zirconia yimpahla enegunya eliphezulu lomatshini kunye nokuqina kwe-fracture kwiqondo lokushisa. I-zirconia yethu (i-ZrO2) yongezwa kunye ne-3mol% Y2O3 i-zirconia esisigxina (i-PSZ). Ngenxa yokuba i-particle diameter ye-PSZ incinci, inokucutshungulwa ngokuchaneka okuphezulu, kwaye ukusetyenziswa kwayo kwiindawo ezichanekileyo ze-machining ezifana nokubumba kuyanda. Ukongeza, ingasetyenziselwa izixhobo zamashishini, iinxalenye ze-optical connector kunye nesixhobo sokutyumza esiphakathi. Ukuqina okuphezulu kwe-PSZ kungasetyenziselwa ukwenza imithombo ekhethekileyo, kwaye isetyenziswa ngokubanzi kwiimela ze-ceramic zasekhaya, i-slicer kunye nezinye iindawo.
Iimpawu eziphambili zeengxenye ze-ceramic zirconia:
1. Ukumelana nokunxiba okugqwesileyo, kuphezulu kakhulu ngamaxesha angama-276 kunentsimbi engenasici
2. Uxinaniso oluphezulu kunobuninzi beekeramics zobugcisa, ngaphezu kwe-6 g / cm3
3. Ubulukhuni obuphezulu, ngaphezu kwe-1300 MPa yeVicker
4. Inokumelana namaqondo aphezulu ukuya kwi-2400 °
5. Ukuhanjiswa kwe-thermal ephantsi, ngaphantsi kwe-3 W / mk kwiqondo lokushisa
6. I-coefficient efanayo yokwandiswa kwe-thermal njengensimbi engenasici
7. Ukuqina kokwaphuka okungaqhelekanga kufikelela kwi-8 Mpa m1/2
8. I-inertness ye-Chemical, ukumelana nokuguga, kwaye kungekhona ukugqwala ngonaphakade
9. Ukumelana neentsimbi ezinyibilikisiweyo ngenxa yeqondo lokunyibilika elingaqhelekanga.

I-Zirconia (ZrO2) Ndiyisebenzisa kakhulu
Izixhobo zokubumba kunye ne-mold (iintlobo ezahlukeneyo zokubumba, ukulungiswa kwendawo echanekileyo, ukulungiswa kwe-insulation); Amalungu okusila (umdidiyeli, ilitye lokusila lokuhamba komoya, ilitye lokusila); Isixhobo semizi-mveliso (i-industrial cutter, i-slitter machine, i-flat press roll); Amacandelo okudibanisa okubonakalayo (umsesane wokutywina, umkhono, ukulungiswa kwe-V-groove); Intwasahlobo ekhethekileyo (i-coil spring, i-plate spring); Iimveliso zabathengi (i-screwdriver encinci ye-insulated, imela ye-ceramic, i-slicer).
