Ubushyuhe bwo hejuru cyane ceramic ceramic material 3YSZ, cyangwa icyo twakwita tetragonal zirconia polycrystal (TZP), ikozwe muri oxyde ya zirconium yatunganijwe na 3% mol yttrium oxyde.

Aya manota ya zirconi afite ingano ntoya nuburemere bukomeye mubushyuhe bwicyumba kuva hafi ya tetragonal. Ingano ntoya (sub-micron) ingano yintete ituma bishoboka kugera ku buso buhebuje burangiza no gukomeza inkombe ityaye.

Zirconiya ikoreshwa kenshi nka stabilisateur hamwe na MgO, CaO, cyangwa Yttria kugirango iteze imbere inzibacyuho. Aho kugirango isohokane ryambere ritanga tetragonal rwose ya kristu yububiko, ibi birema igice cya cubic kristaliste igereranywa no gukonja. Imvura ya Tetragonal ihura nimpinduka ziterwa nimpinduka zicyiciro cyegereye intambwe igenda itera ingaruka. Iyi nzira itera imiterere kwaguka mugihe ikuramo ingufu zitari nke, zikaba zibara ubukana budasanzwe. Ubushyuhe bwo hejuru nabwo butera umubare munini wo kuvugurura, bigira ingaruka mbi ku mbaraga kandi bigatera kwaguka kwa 3-7%. Mugushyiramo imvange yavuzwe haruguru, ingano ya tetragonal irashobora gucungwa kugirango habeho kuringaniza hagati yo gukomera no gutakaza imbaraga.

Ku bushyuhe bwicyumba, tetragonal zirconia ihagaze neza hamwe na 3 mol% Y2O3 (Y-TZP) yerekana imikorere myiza mubijyanye no gukomera, imbaraga zunamye. Irerekana kandi ibintu nka ionic conducivite, ubushyuhe buke bwumuriro, gukomera nyuma yo guhinduka, hamwe nuburyo bwo kwibuka. Tetragonal zirconia ituma bishoboka gukora ibice bya ceramic bifite imbaraga zo kurwanya ruswa, kwihanganira kwambara neza, no kurangiza neza.

Ubu bwoko bwimiterere butuma bushobora gukoreshwa cyane mubice nka biomedical field yo guhindagura ikibuno no kongera amenyo, no mumurima wa kirimbuzi nkigice cya barrière yumuriro mubitereko bya peteroli.
