Yttria waxay xasilisay zirconia, YSZ waa nooc ka mid ah walxaha dhoobada ah. Marka lagu daro Yttrium (III) oxide, heerka isbeddelka heerkulka kala duwan ee Zirconium dioxide waa la bedeli karaa si loo soo saaro crystals cubic xasilloon iyo kiristaalo tetragonal heerkulka qolka.
Zirconia saafi ah waa wejiga monokilin ee heerkulka qolka. Marka heerkulku kor u kaco ilaa 1173 ℃, waxa uu isu beddeli doonaa weji tetragonal ah, marka uu kor u kaco 2370 ℃, waxa uu isu beddeli doonaa weji cubic ah. At 2690 ℃, waxay noqon doontaa weji dareere ah.
Marxaladda monoclinic (heerkulka isbeddelka wejiga: 1173 ° C) wejiga tetragonal (heerkulka isbeddelka wejiga: 2370 ° C) wejiga cubic (dhibcaha dhalaalka / dhibicda adkaynta: 2690 ° C) dareere.
Zirconia saafi ah waxaa lagu qaboojiyaa heerkul sare ilaa heerkulka qolka, ka dib marka la maro heerkulka isbeddelka wajiga, crystal square ayaa loo beddelaa kareemka monoclinic. Isbeddelka mugga ba'an awgeed, badeecada sintay waxay ka kooban tahay microcracks oo badanaa lama isticmaali karo. Zirconium dioxide kuma jiraan wejiga cubic (qaab dhismeedka crystal fluorite) heerkulka qolka, laakiin marka lagu daro oksaydhyada kale, kala duwanaanta heerkulka Zirconium dioxide xasilin ee wajiga cubic si weyn ayaa loo kordhin karaa. Zirconium dioxide-ka lagu daro oo lagu dajiyay stabilizer wajiga waxaa loo yaqaan zirkoniyas xasiloon.
Kuulaha zirconia ee xasiloon ee Yttrium waxaa loo isticmaali karaa Electroceramics, qalabka magnetic, zirconia, silicon oxide, Zirconium (IV) silicate, titanium dioxide, cuntada dawooyinka, midabada, midabada, khadyada, iyo warshadaha kiimikada gaarka ah. Qalabka dib-u-soo-celinta ee Zirconia: Crucibles zirconia, fiilooyinka refractory zirconia, qalabka kiln ee zirconia. dhoobada qaab dhismeedka Zirconia: Xargaha dhoobada zirconia, tuubooyinka dhoobada zirconia, agabka wax lagu shiido zirconia. dhoobada functional Zirconia: zirconia dhoobada dhoobada qalimaan ballpoint, zirconia qalabka dhoobada, Zirconia qalabka kululaynta heerkulka sare, zirconia bioceramics, zirconia qalabka daahan, Zirconia qalabka isgaarsiinta, zirconia oksijiin dareemayaal.
Waxaan soo saareynaa budada YSZ iyada oo loo marayo habka is-faafinta ee hidrolysis. Iyada oo ku saleysan maadooyinka kala duwan ee Y2O3, waxaan soo saari karnaa budada YSZ ee kala duwan. Badeecadaha caadiga ah waa budada 3Y-YSZ, oo loo qaybiyay budada isku dhafan iyo budada aan la isku dhejin iyadoo ku xiran shuruudaha macaamiisha Guryaha jireed waxay buuxin karaan shuruudaha kala duwan ee macaamiisha ee cadaadiska qalalan, riixida isostatic, duritaanka, shubista, qaabaynta duritaanka, shubista sibidhka iyo wixii la mid ah.
