I-Yttria izinzile i-zirconia, i-YSZ luhlobo lwemathiriyeli ye-ceramic. Ngokongeza i-Yttrium (III) i-oxide, iqondo lokushisa lokuguqulwa kwesigaba se-Zirconium dioxide lingatshintshwa ukuvelisa iikristale ze-cubic ezizinzile kunye ne-tetragonal crystals kwiqondo lokushisa.
I-zirconia ecocekileyo yinqanaba le-monoclinic kwiqondo lokushisa. Xa iqondo lobushushu linyuka ukuya malunga ne-1173 ℃, liyakutshintsha libe kwisigaba se-tetragonal, kwaye xa linyuka liye kwi-2370 ℃, liya kutshintsha libe yi-cubic phase. Kwi-2690 ℃, iya kuba sisigaba solwelo.
Isigaba se-Monoclinic (iqondo lotshintsho lwesigaba: 1173 ° C) isigaba se-tetragonal (iqondo lokutshintsha isigaba: 2370 ° C) isigaba se-cubic (indawo yokunyibilika/indawo yokuqinisa: 2690 ° C) ulwelo.
I-zirconia ecocekileyo ipholile ukusuka kwiqondo lokushisa eliphezulu ukuya kwiqondo lokushisa, kwaye emva kokushisa kwesigaba sokuguqulwa, i-crystal yesikwere iguqulwa ibe yikristale ye-monoclinic. Ngenxa yokutshintsha komthamo omkhulu, imveliso ye-sintered iqulethe i-microcracks kwaye ihlala ingasetyenziswa. I-Zirconium dioxide ayikho kwi-cubic phase (i-crystal structure ye-fluorite) kwiqondo lokushisa lokushisa, kodwa ngokongeza ezinye i-oxides, uluhlu lweqondo lokushisa lwe-Zirconium dioxide oluzinzile kwisigaba se-cubic lunokwandiswa kakhulu. I-Zirconium dioxide efakwe kwi-stabilizer yesigaba ibizwa ngokuba zirconias ezizinzileyo.
I-Yttrium ezinzile i-zirconia beads ingasetyenziswa kwi-Electroceramics, izinto eziphathekayo, i-zirconia, i-silicon oxide, i-Zirconium (IV) i-silicate, i-titanium dioxide, ukutya kwamayeza, ii-pigments, iidayi, ii-inki kunye namashishini akhethekileyo amachiza. I-Zirconia refractory materials: ii-zirconia crucibles, i-zirconia refractory fibers, i-zirconia kiln materials. I-Zirconia structural ceramics: iibheringi ze-zirconia ze-ceramic, i-zirconia ze-ceramic valves, i-zirconia yokugaya izinto. I-zirconia ceramics esebenzayo: iibhola ze-ceramic ze-zirconia ze-ceramic zokubhala i-ballpoint, izixhobo ze-zirconia ze-ceramic, i-zirconia yobushushu obuphezulu bezinto zokufudumeza, i-zirconia bioceramics, izinto zokugquma i-zirconia, izixhobo zonxibelelwano ze-zirconia, i-zirconia oxygen sensors.
Sivelisa i-YSZ powder ngokuzizalisa inkqubo ye-hydrolysis.Ngokusekelwe kwimixholo eyahlukeneyo ye-Y2O3, sinokuvelisa i-YSZ yomgubo ohlukeneyo.Imveliso eqhelekileyo i-3Y-YSZ i-powder-based, ihlukaniswe ibe ngumgubo odibeneyo kunye nomgubo ongaxutywanga ngokuxhomekeke kwiimfuno zabathengi. .Iipropati ezibonakalayo zinokuhlangabezana neemfuno ezahlukeneyo zabathengi zokucinezela okomileyo, ukucofa isostatic, isitofu, ukuphosa, ukubunjwa kwesitofu, ukuphosa ukuphosa njalo njalo.
