Zirconium oxide (ZrO₂), inozivikanwawo se zirconium dioxide, chinhu chakakosha checeramic chinoshanda zvakanyanya. Iupfu chena kana yero yakajeka ine hunhu hwakanaka hwemuviri uye hwemakemikari. Zirconia ine poindi yekunyunguduka inosvika 2700°C, kuomarara kwakanyanya, simba remuchina rakawanda, kugadzikana kwakanaka kwekupisa uye kugadzikana kwemakemikari, uye inogona kutsungirira ngura yeacid nealkali uye tembiricha yepamusoro. Pamusoro pezvo, zirconium oxide ine indekisi yepamusoro ye refractive uye hunhu hwakanaka hwe optical, saka inoshandiswawo zvakanyanya mumunda we optical.
Mumashandisirwo anoshanda, purezirconium oxideine matambudziko ekuchinja kwechikamu (kuchinja kubva pachikamu chemonoclinic kuenda kuchikamu chetetragonal kunokonzera shanduko yevhoriyamu uye kutsemuka kwezvinhu), saka zvinowanzo dikanwa kugadzira zvigadzikisi zvakaita seyttrium oxide (Y₂O₃), calcium oxide (CaO) kana magnesium oxide (MgO) kuti igadzire zirconium oxide yakagadzikana (Stabilized Zirconia) kuti ivandudze hunhu hwayo hwemakanika uye kuramba kupisa. Kuburikidza nemaitiro ekushandisa zvinodhaka uye sintering, zvinhu zvezirconia hazvingogone kuchengetedza hunhu hwakanaka hwemakanika chete, asiwo kuratidza conductivity yakanaka yeionic, izvo zvinoita kuti ishandiswe zvakanyanya mu structural ceramics, fuel cells, oxygen sensors, medical implants nedzimwe nzvimbo.
Kuwedzera pakushandiswa kwezvinhu zvechinyakare zvekuvaka, zirconia inewo basa rakakosha mumunda wekugadzirisa pamusoro zvakanyatsonaka, kunyanya mumunda wezvinhu zvekupukuta zvepamusoro. Nehunhu hwayo hwakasiyana, zirconia yave chinhu chakakosha pakupukuta nemazvo.
Mubasa rekukwesha,zirconiainonyanya kushandiswa sehupfu hwekupukuta hwepamusoro-soro uye slurry yekupukuta. Nekuda kwekuoma kwayo kuri pakati nepakati (kuoma kweMohs kweinenge 8.5), simba rakawanda remakanika uye kusagadzikana kwakanaka kwemakemikari, zirconia inogona kuwana kusarongeka kwepamusoro-soro uku ichivimbisa mwero wekupukuta wakakwira, uye kuwana kupera kwakaenzana negirazi. Kana ichienzaniswa nezvinhu zvekupukuta zvechinyakare zvakaita sealuminium oxide necerium oxide, zirconia inogona kuenzanisa mwero wekubvisa zvinhu uye kunaka kwenzvimbo panguva yekupukuta, uye inzvimbo yakakosha yekupukuta mumunda wekugadzira zvakanyatsonaka.
Upfu hwekupukuta hweZirconia hunowanzo kuve nehukuru hwezvimedu zvinodzorwa pakati pe0.05μm ne1μm, izvo zvakakodzera kupukuta pamusoro pezvinhu zvakasiyana-siyana zvine hungwaru. Nzvimbo dzayo huru dzekushandisa dzinosanganisira: girazi re optical, lenzi dzemakamera, girazi refoni, hard disk substrates, LED sapphire substrates, zvinhu zvesimbi zvepamusoro (zvakadai se titanium alloys, simbi isina ngura, zvishongo zvesimbi zvinokosha) uye zvishandiso zve ceramic zvepamusoro (zvakadai se alumina ceramics, silicon nitride ceramics, nezvimwewo). Mukushandiswa uku,zirconium oxideUpfu hwekupukuta hunogona kuderedza zvikanganiso zvepadenga uye kuvandudza mashandiro emaziso uye kugadzikana kwemuchina wezvigadzirwa.
Kuti zvizadzise zvinodiwa nemaitiro akasiyana ekupukuta,zirconium oxideinogona kugadzirwa kuita upfu hwekupukuta humwe chete, kana kuti inogona kusanganiswa nezvimwe zvinhu zvekupukuta (zvakaita secerium oxide, aluminium oxide) kuti igadzire slurry yekupukuta ine mashandiro ari nani. Pamusoro pezvo, slurry yekupukuta ye zirconium oxide yakachena kwazvo inowanzoshandisa tekinoroji yekupararira kwe nano-dispersion kuti iite kuti zvidimbu zvipararire zvakanyanya mumvura kudzivirira kuungana, kuve nechokwadi chekugadzikana kwemaitiro ekupukuta uye kufanana kwenzvimbo yekupedzisira.
Zvose, nekuvandudzwa kuri kuramba kuchiitwa kwezvinodiwa zvemhando yepamusoro mu tekinoroji yeruzivo rwemagetsi, kugadzira maziso, nzvimbo dzemuchadenga uye nzvimbo dzekurapa dzemhando yepamusoro,zirconium oxide, semhando itsva yezvinhu zvekupukuta zvinobudirira zvikuru, ine mukana wakakura wekushandisa. Mune ramangwana, nekuvandudzwa kuri kuitwa tekinoroji yekugadzira zvinhu nemazvo, kushandiswa kwehunyanzvi hwezirconium oxide mumunda wekupukuta kucharamba kuchidzika, zvichibatsira kusangana nezvinodiwa zvekugadzira zvepamusoro.
