I-Yttria ezinzile i-zirconia, i-YSZ iwuhlobo lwempahla yobumba. Ngokungeza i-Yttrium(III) oxide, izinga lokushisa lokuguqulwa kwesigaba se-Zirconium dioxide lingashintshwa ukuze likhiqize amakristalu e-cubic azinzile kanye namakristalu e-tetragonal ekamelweni lokushisa.
I-zirconia ehlanzekile yisigaba se-monoclinic ekamelweni lokushisa. Lapho izinga lokushisa likhuphuka lifinyelela cishe ku-1173 ℃, lizoshintsha libe yisigaba se-tetragonal, futhi lapho likhuphukela ku-2370 ℃, lizoshintsha libe yisigaba se-cubic. Ku-2690 ℃, izoba yisigaba soketshezi.
Isigaba se-Monoclinic (izinga lokushisa lokuguqulwa kwesigaba: 1173 ° C) isigaba se-tetragonal (izinga lokushisa lokuguqulwa kwesigaba: 2370 ° C) isigaba se-cubic (iphoyinti lokuncibilika/iphuzu lokuhlanganisa: 2690 ° C) uketshezi.
I-zirconia ehlanzekile ipholile kusukela ekushiseni okuphezulu kuya ekamelweni lokushisa, futhi ngemva kokuthola izinga lokushisa lokuguqulwa kwesigaba, ikristalu yesikwele iguqulwa ibe yikristalu ye-monoclinic. Ngenxa yoshintsho olukhulu lwevolumu, umkhiqizo we-sintered uqukethe ama-microcracks futhi ngokuvamile awusebenziseki. I-Zirconium dioxide ayikho esigabeni se-cubic (isakhiwo sekristalu ye-fluorite) ekamelweni lokushisa, kodwa ngokungeza amanye ama-oxides, izinga lokushisa le-Zirconium dioxide elizinzile esigabeni se-cubic lingakhuphuka kakhulu. I-Zirconium dioxide ehlanganiswe ne-stabilizer yesigaba ibizwa ngokuthi i-zirconias ezinzile.
Ubuhlalu be-zirconia obuqinile be-Yttrium bungasetshenziswa ku-Electroceramics, izinto zikazibuthe, i-zirconia, i-silicon oxide, i-Zirconium(IV) silicate, i-titanium dioxide, ukudla kwemithi, izingulube, odayi, oyinki, nezimboni zamakhemikhali ezikhethekile. I-Zirconia refractory materials: i-zirconia crucibles, i-zirconia refractory fibers, i-zirconia kiln materials. I-Zirconia structural Ceramics: i-zirconia ceramic bearings, i-zirconia ceramic valves, izinto zokugaya i-zirconia. I-Zirconia Ceramics esebenzayo: amabhola e-zirconia ceramic amapeni e-ballpoint, amathuluzi e-zirconia ceramic, izinto zokushisa ezishisa kakhulu ze-zirconia, i-zirconia bioceramics, izinto zokumboza i-zirconia, izinto zokuxhumana ze-zirconia, izinzwa ze-oxygen zirconia.
Sikhiqiza i-YSZ powder ngokuzisakaza inqubo ye-hydrolysis.Ngokusekelwe kokuqukethwe okuhlukene kwe-Y2O3, singakhiqiza i-YSZ powder ehlukile.Imikhiqizo evamile i-3Y-YSZ powder-based, ihlukaniswe yaba yimpushana ehlanganisiwe kanye nempushana engahlanganisiwe kuye ngezidingo zamakhasimende. .Izakhiwo ezibonakalayo zingahlangabezana nezidingo ezihlukile zamakhasimende zokucindezela okomile, ukucindezela kwe-isostatic, umjovo, ukuphonsa, ukubumba umjovo, ukuphonsa iziliphu nokunye.
