Zirconium oxide (ZrO₂), inozivikanwawo se zirconium dioxide, chinhu chakakosha chepamusoro-chekuita ceramic zvinhu. Ihwo hupfu huchena kana hunyoro hweyero hune hunyoro hwakanaka hwemuviri nemakemikari. Zirconia ine nzvimbo yakanyunguduka inenge 2700 ° C, kuoma kwepamusoro, kusimba kwepamusoro kwemagetsi, kugadzikana kwakanaka kwekushisa uye kugadzikana kwemakemikari, uye inogona kumira asidi uye alkali corrosion uye nzvimbo dzekushisa kwepamusoro. Mukuwedzera, zirconium oxide ine yakakwira refractive index uye yakanakisa optical properties, saka inoshandiswawo zvakanyanya mundima yemaziso.
Mukushanda kwekushandisa, yakachenazirconium oxideine matambudziko ekuchinja kwechikamu (kushanduka kubva kuchikamu chemonoclinic kuenda kuchikamu chetetragonal kuchaita kuti vhoriyamu ishanduke uye kutsemuka kwezvinhu), saka kazhinji zvinodiwa kuti dope stabilizers seyttrium oxide (Y₂O₃), calcium oxide (CaO) kana magnesium oxide (MgO) kuita yakagadzikana zirconium mechanical oxide (Yakadzikama yekusagadzikana kweZirconia). Kuburikidza neinonzwisisika doping uye sintering maitiro, zirconia zvinhu hazvigone chete kuchengetedza yakanakisa michina zvivakwa, asi zvakare kuratidza yakanaka ionic conductivity, iyo inoita kuti ishandiswe zvakanyanya mukugadzira ceramics, masero emafuta, okisijeni sensors, kuisirwa kwekurapa uye mamwe minda.
Kuwedzera kune echinyakare zvimiro zvekushandisa zvekushandisa, zirconia inoitawo basa rinowedzera kukosha mumunda we Ultra-chaiyo yepamusoro kurapwa, kunyanya mumunda wepamusoro-yekupedzisira polishing zvinhu. Nezvayo zvakasarudzika zvemuviri zvimiro, zirconia yave chinhu chakakosha chinhu chakakosha pakukwenenzvera.
Mundima yekukwenenzvera.zirconiainonyanya kushandiswa seyepamusoro-yekupedzisira poridhe yehupfu uye yekupukuta slurry. Nekuda kwekuoma kwayo kuri pakati nepakati (kuoma kweMohs kunosvika 8.5), kusimba kwemechanicha yepamusoro uye kunaka kwemakemikari inertness, zirconia inogona kuwana yakaderera zvakanyanya kushata kwepamusoro uku ichichengetedza chiyero chepamusoro chekupenya, uye kuwana girazi-level kupera. Kana ichienzaniswa neyechinyakare kupukuta zvinhu zvakaita sealuminium oxide uye cerium oxide, zirconia inokwanisa kuenzanisa chiyero chekubvisa zvinhu uye kunaka kwepamusoro panguva yekupenya, uye yakakosha kupukuta svikiro mumunda we Ultra-chaizvo kugadzira.
Zirconia polishing poda kazhinji ine particle size inodzorwa pakati pe 0.05μm ne 1μm, iyo inokodzera kupenya kwepamusoro kwezvinhu zvakasiyana-siyana zvemhando yepamusoro. Nzvimbo dzayo huru dzekushandisa dzinosanganisira: girazi remaziso, lenzi dzekamera, girazi renhare mbozha, hard disk substrates, LED sapphire substrates, yakakwirira-yekupedzisira simbi zvinhu (senge titanium alloys, simbi isina tsvina, yakakosha simbi zvishongo) uye advanced ceramic zvishandiso (senge alumina ceramics, silicon nitride ceramics, nezvimwewo). Muzvikumbiro izvi,zirconium oxidepolishing poda inogona kunyatso kudzikisa kuremara kwepasi uye kugadzirisa optical performance uye mechanical kugadzikana kwezvigadzirwa.
Kuti usangane nezvinodiwa zvakasiyana-siyana zvekupenya maitiro,zirconium oxideinogona kugadzirwa kuva poda yekupukuta imwe chete, kana kuti inogona kusanganiswa nezvimwe zvinhu zvekukwenenzvera (senge cerium oxide, aluminium oxide) kuita slurry yekupukuta nekuita zvirinani. Uye zvakare, yakakwira-kuchena zirconium oxide polishing slurry kazhinji inotora nano-kupararira tekinoroji kuita kuti zvimedu zvipararire zvakanyanya mumvura kuti zvidzivise kusanganiswa, kuve nechokwadi chekugadzikana kweiyo polishing maitiro uye kufanana kweiyo yekupedzisira nzvimbo.
Pakazere, nekuenderera mberi kwekuvandudza kwemhando yepamusoro zvinodiwa mumagetsi ruzivo tekinoroji, optical kugadzira, aerospace uye yakakwirira-yekupedzisira minda yekurapa,zirconium oxide, serudzi rutsva rwemhando yepamusoro-yekukwenenzvera zvinhu, ine tarisiro yakafara kwazvo yekushandisa. Mune ramangwana, nekuenderera mberi kwekuvandudza tekinoroji ye-ultra-precision machining, iyo tekinoroji yekushandisa ye zirconium oxide mumunda wekupukuta icharamba ichidzika, ichibatsira kuzadzisa zvinodiwa zvekugadzira zvepamusoro.
