Yttria yakagadzikana zirconia, YSZ imhando yezvinhu zveceramic. Nekuwedzera Yttrium(III) oxide, iyo chikamu chekushandura tembiricha yeZirconium dioxide inogona kuchinjwa kuti ibudise yakagadzika cubic crystals uye tetragonal crystals pakamuri tembiricha.
Pure zirconia chikamu chemonoclinic pakupisa kwekamuri. Kana tembiricha yakwira kusvika pa1173 ℃, inoshanduka kuita tetragonal phase, uye kana yakwira kusvika 2370 ℃, inoshanduka kuita cubic phase. Pa2690 ℃, ichava chikamu chemvura.
Monoclinic phase (phase transformation tembiricha: 1173 ° C) tetragonal phase (phase shanduko tembiricha: 2370 ° C) cubic phase (melting point/solidification point: 2690 ° C) mvura.
Yakachena zirconia yakanyoroveswa kubva kune yakakwira tembiricha kusvika kukamuri tembiricha, uye mushure mekuita chikamu chekushandura tembiricha, iyo square crystal inoshandurwa kuita monoclinic crystal. Nekuda kwekushanduka kwayo kwevhoriyamu, iyo sintered chigadzirwa ine microcracks uye kazhinji haigoneke. Zirconium dioxide haipo mu cubic phase (fluorite crystal structure) pane tembiricha yekamuri, asi nekuwedzera mamwe maokisi, tembiricha yeZirconium dioxide yakagadzikana mu cubic phase inogona kuwedzera zvakanyanya. Iyo Zirconium dioxide yakavharwa ne phase stabilizer inonzi stabilized zirconias.
Yttrium yakagadzikana zirconia beads inogona kushandiswa muElectroceramics, magineti zvinhu, zirconia, silicon oxide, Zirconium (IV) silicate, titanium dioxide, chikafu chemishonga, pigments, dhayi, ingi, uye akakosha maindasitiri emakemikari. Zirconia refractory zvinhu: zirconia crucibles, zirconia refractory fibers, zirconia kiln zvinhu. Zirconia structural ceramics: zirconia ceramic bearings, zirconia ceramic valves, zirconia grinding materials. Zirconia functional ceramics: zirconia ceramic balls for ballpoint pen, zirconia ceramic tools, zirconia high-temperature heat materials, zirconia bioceramics, zirconia coating materials, zirconia communication materials, zirconia oxygen sensors.
Isu tinogadzira YSZ hupfu nekuzviparira hydrolysis process.Kubva pane zvakasiyana zveY2O3, tinogona kugadzira akasiyana YSZ hupfu.Normal zvigadzirwa ndeye 3Y-YSZ poda-yakavakirwa, yakakamurwa kuita compact poda uye isina-yakaomeswa poda zvinoenderana nezvinodiwa nevatengi. .Zvinhu zvemuviri zvinogona kusangana necustomer'different zvinodiwa zvekutsikirira yakaoma, isostatic kudzvanya, jekiseni, kukanda, jekiseni kuumba, kutsvedza kukanda uye zvichingodaro.
