Zirconia chinhu chine yakakwira mechaniki simba uye kutsemuka kuomarara pakudziya kwekamuri.Yedu zirconia (ZrO2) inowedzerwa ne3mol% Y2O3 partial stable zirconia (PSZ).Nekuti iyo chidimbu dhayamita yePSZ zvinhu idiki, inogona kugadziriswa nekurongeka kwepamusoro, uye kushandiswa kwayo mune chaiyo machining zvikamu senge molds iri kuwedzera.Uye zvakare, inogona zvakare kushandiswa kune maindasitiri maturusi, optical connector zvikamu uye kupwanya michina yepakati.Iyo yakanyanya kutsemuka kuomarara kwePSZ inogona kushandiswa kugadzira yakakosha zvitubu, uye zvakare inoshandiswa zvakanyanya mudzimba dzeceramic mapanga, slicer uye zvimwe zvikamu.
Hunhu hukuru hwe zirconia ceramic zvikamu:
1. Yakanakisa kupfeka kuramba, yakanyanya kukwirira 276 nguva pane simbi isina tsvina
2. Yakakwirira density kupfuura akawanda technical ceramics, kupfuura 6 g/cm3
3. Kuoma kwepamusoro, pamusoro pe1300 MPa yeVicker
4. Inogona kumira tembiricha yepamusoro kusvika 2400°
5. Low thermal conductivity, isingasviki 3 W / mk pakushambidzika kwekamuri
6. Yakafanana coefficient of thermal kuwedzera sesimbi isina tsvina
7. Kutyoka kunoshamisa kunosvika pa8 Mpa m1/2
8. Chemical inertness, kuchembera kuramba, uye kwete ngura nokusingaperi
9. Kuramba simbi yakanyungudutswa nekuda kwekunyungudika kunoshamisa.
