I-Zirconium oxide (ZrO₂), ekwaziwa ngokuba yi-zirconium dioxide, sisixhobo esibalulekileyo se-ceramic esisebenza kakuhle. Yipowder emhlophe okanye etyheli ekhanyayo eneempawu zomzimba nezekhemikhali ezibalaseleyo. I-Zirconia inendawo yokunyibilika emalunga ne-2700°C, ubulukhuni obuphezulu, amandla aphezulu oomatshini, uzinzo oluhle lobushushu kunye nozinzo lweekhemikhali, kwaye inokumelana nokugqwala kwe-asidi kunye ne-alkali kunye neendawo zobushushu obuphezulu. Ukongeza, i-zirconium oxide ine-refractive index ephezulu kunye neempawu ezibonakalayo ezibalaseleyo, ngoko ke ikwasetyenziswa kakhulu kwintsimi ye-optical.
Kwizicelo ezisebenzayo,i-zirconium oxideineengxaki zokutshintsha kwesigaba (utshintsho ukusuka kwisigaba se-monoclinic ukuya kwisigaba se-tetragonal luya kubangela utshintsho lomthamo kunye nokuqhekeka kwezinto), ngoko ke kudla ngokuba yimfuneko ukwenza iziqinisi ezifana ne-yttrium oxide (Y₂O₃), i-calcium oxide (CaO) okanye i-magnesium oxide (MgO) ukwenza i-zirconium oxide ezinzileyo (i-Zirconia ezinzileyo) ukuphucula iipropati zayo zoomatshini kunye nokumelana nobushushu. Ngokusebenzisa iinkqubo ezifanelekileyo zokusebenzisa i-doping kunye ne-sintering, izixhobo ze-zirconia azinakugcina kuphela iipropati zoomatshini ezilungileyo, kodwa zikwabonisa ukuqhuba kakuhle kwe-ionic, okwenza ukuba isetyenziswe kakhulu kwi-ceramics zesakhiwo, ii-fuel cells, ii-oxygen sensors, ii-implants zonyango kunye nezinye iindawo.
Ukongeza kwizicelo zemveli zezixhobo zokwakha, i-zirconia ikwadlala indima ebaluleke ngakumbi kwicandelo lonyango lomphezulu oluchanekileyo kakhulu, ngakumbi kwicandelo lezinto zokupholisha eziphezulu. Ngenxa yeempawu zayo zomzimba ezikhethekileyo, i-zirconia ibe yinto ebalulekileyo efunekayo ekupholiseni ngokuchanekileyo.
Kwicandelo lokupholisha,i-zirconiaIsetyenziswa kakhulu njengepowder yokupolisha ephezulu kunye ne-slurry yokupolisha. Ngenxa yobunzima bayo obuphakathi (ubulukhuni beMohs obumalunga ne-8.5), amandla aphezulu oomatshini kunye nokungasebenzi kakuhle kweekhemikhali, i-zirconia inokufikelela kuburhabaxa bomphezulu obuphantsi kakhulu ngelixa iqinisekisa izinga eliphezulu lokupolisha, kwaye ifumane ukugqitywa kwinqanaba lesipili. Xa kuthelekiswa nezixhobo zokupolisha zendabuko ezifana ne-aluminium oxide kunye ne-cerium oxide, i-zirconia inokulinganisela ngcono izinga lokususwa kwezinto kunye nomgangatho womphezulu ngexesha lenkqubo yokupolisha, kwaye yindawo ebalulekileyo yokupolisha kwicandelo lokuvelisa ngokuchanekileyo kakhulu.
I-Zirconia polishing powder ngokubanzi inobungakanani be-particle obulawulwa phakathi kwe-0.05μm kunye ne-1μm, efanelekileyo ekupolisheni umphezulu wezinto ezahlukeneyo ezichanekileyo. Iindawo zayo eziphambili zokusetyenziswa ziquka: iglasi ebonakalayo, iilensi zekhamera, iglasi yesikrini sefowuni ephathwayo, ii-substrates zediski enzima, ii-substrates ze-LED zesafire, izinto zesinyithi eziphezulu (ezifana ne-titanium alloys, intsimbi engagqwaliyo, ubucwebe besinyithi esixabisekileyo) kunye nezixhobo zeseramikhi eziphambili (ezifana ne-alumina ceramics, i-silicon nitride ceramics, njl.njl.). Kwezi zicelo,i-zirconium oxideUmgubo wokupholisha unokunciphisa ngempumelelo iziphene zomphezulu kwaye uphucule ukusebenza kokukhanya kunye nokuzinza koomatshini kweemveliso.
Ukuze kuhlangatyezwane neemfuno zeenkqubo ezahlukeneyo zokupholisha,i-zirconium oxideingenziwa ibe yipowder enye yokupolisha, okanye ingadityaniswa nezinye izinto zokupolisha (ezifana ne-cerium oxide, i-aluminium oxide) ukuze kwenziwe i-slurry yokupolisha esebenza ngcono. Ukongeza, i-slurry yokupolisha ye-zirconium oxide ecocekileyo kakhulu idla ngokusebenzisa itekhnoloji ye-nano-dispersion ukwenza amasuntswana asasazeke kakhulu kulwelo ukuze kuthintelwe ukuhlangana, kuqinisekiswe uzinzo lwenkqubo yokupolisha kunye nokufana komphezulu wokugqibela.
Lilonke, ngokuphuculwa okuqhubekayo kweemfuno zomgangatho womphezulu kwitekhnoloji yolwazi lwe-elektroniki, ukuveliswa kwezinto ezibonakalayo, i-aerospace kunye namacandelo ezonyango akumgangatho ophezulu,i-zirconium oxide, njengohlobo olutsha lwezinto zokupolisha ezisebenzayo kakhulu, lunendlela ebanzi kakhulu yokusetyenziswa. Kwixesha elizayo, ngophuhliso oluqhubekayo lwetekhnoloji yoomatshini bokupolisha echanekileyo kakhulu, ukusetyenziswa kobugcisa kwe-zirconium oxide kwicandelo lokupolisha kuya kuqhubeka nzulu, kunceda ukuhlangabezana neemfuno zokuvelisa eziphezulu.
