Yttria ituje zirconiya, YSZ ni ubwoko bwibikoresho bya ceramic. Mugushyiramo okiside ya Yttrium (III), igipimo cyimpinduka yubushyuhe bwa dioxyde ya Zirconium irashobora guhinduka kugirango habeho kristu ihagaze neza hamwe na tetragonal kristaliste mubushyuhe bwicyumba.
Zirconi nziza nicyiciro cya monoclinic mubushyuhe bwicyumba. Iyo ubushyuhe buzamutse bugera kuri 1173 ℃, buzahinduka icyiciro cya tetragonal, kandi iyo kizamutse kigera kuri 2370 ℃, kizahinduka icyiciro kibe. Kuri 2690 ℃, bizahinduka icyiciro cyamazi.
Icyiciro cya Monoclinike (ubushyuhe bwo guhindura icyiciro: 1173 ° C) icyiciro cya tetragonal (ubushyuhe bwo guhindura icyiciro: 2370 ° C) icyiciro cya cubic (gushonga / gukomera: 2690 ° C) amazi.
Zirconi nziza ikonjeshwa kuva ubushyuhe bwo hejuru ikagera ku bushyuhe bwicyumba, kandi nyuma yubushyuhe bwo guhindura icyiciro, kirisiti ya kare ihindurwamo kristu ya monoclinic. Bitewe nubunini bukabije bwahindutse, ibicuruzwa byacumuye birimo microcrack kandi akenshi ntibikoreshwa. Dioxyde ya Zirconium ntabwo ibaho mugice cya cubic (imiterere ya fluorite ya kristu) mubushyuhe bwicyumba, ariko wongeyeho izindi oxyde, ubushyuhe bwa dioxyde ya Zirconium ihagaze mugice cya cubic irashobora kwiyongera cyane. Dioxyde ya Zirconium yuzuye hamwe na stabilisateur ya fonction yitwa zirconi stabilised.
Yttrium itunganijwe neza ya zirconia irashobora gukoreshwa muri Electroceramics, ibikoresho bya magnetiki, zirconi, silicon oxyde, silikatike ya Zirconium (IV), dioxyde de titanium, ibiryo bya farumasi, pigment, amarangi, wino, ninganda zidasanzwe za chimique. Ibikoresho bya Zirconiya bivunika: zirconia crucibles, fibre ya zirconia fibre, ibikoresho bya kilcon ya zirconi. Ububiko bwububiko bwa Zirconiya: zirconia ceramic, zirconia ceramic valve, ibikoresho byo gusya bya zirconi. Ubukorikori bukora bwa Zirconiya: imipira ya ceramic ya zirconi yamakaramu yumupira, ibikoresho bya ceramic zirconia, ibikoresho byo gushyushya ubushyuhe bwa zirconiya, bioceramika ya zirconi, ibikoresho byo gutwikira zirconi, ibikoresho byitumanaho bya zirconi, sensor ya ogisijeni ya zirconi.
Dutanga ifu ya YSZ mukwikwirakwiza hydrolysis inzira. Dushingiye kubintu bitandukanye bya Y2O3, dushobora kubyara ifu ya YSZ itandukanye.Ibicuruzwa bisanzwe ni ifu ya 3Y-YSZ, igabanijwemo ifu yuzuye hamwe nifu idahwitse bitewe nibisabwa nabakiriya. .Imiterere yumubiri irashobora kuba yujuje abakiriya ibisabwa bitandukanye kugirango bakande byumye, gukanda isostatike, gutera inshinge, gutera inshinge, guterera inshinge nibindi.
