Uphuhliso olukhawulezileyo kwicandelo lolwazi kunye ne-optoelectronition ikhuthaze ukuhlaziywa kwetekhnoloji ye-Powcocial Pleical Playiling (CMP). Ukongeza kwizixhobo kunye nezixhobo, ukufunyanwa kwendawo yokuchaneka ephambili kuxhomekeke kuyilo kunye nokuveliswa kwemizi-mveliso yokuvelisa okusebenza kakuhle, kunye nokulungiswa kwe-slipry ehambelana ne-sliads ehambelana noko. Kwaye ngokuphuculwa okuqhubekayo kokulungiswa kokusebenza okungaphezulu kunye neemfuno zokusebenza kakuhle, iimfuno zezinto ezisebenzayo zokuSebenza eziSebenzayo nazo ziyaphakama nangaphezulu. I-Cerium Daioxide isetyenziswe ngokubanzi kumatshini wokuchaneka kwe-murdeckoction kunye nezinto ezichanekileyo.
I-cerium oxide powder (vk-vk-vk-ch.
Iipropati ezisisiseko zeCirium Oxide:
ICiria ebizwa ngokuba yi-cerium oxide, yi-oxiide ye-cerium. Ngeli xesha, ukuvutha kwe-cirium ngu-7, kwaye ifomula yekhemikhali yi-CEO2. Imveliso ecocekileyo iMhlophe umgubo onzima okanye i-cubic systic, kunye nemveliso yokungacoceki ityheli okanye ipinki i-pink yomgubo (kuba iqulethe umkhondo weLanthanum, njl njl.). Kubushushu begumbi kunye noxinzelelo, i-ciaria sisimo se-cirium. I-Cerium inokufowuni +3 Valence CEC2O3, engazinzanga kwaye iya kwenza izithembiso zika-CEO2 nge-O2. I-Cerium Oxide inyibilika kancinci emanzini, ialkali ne-acid. Ukuxinana kwe-7.132 g / cm3, indawo yokunyibilika ngama-2600 ℃, kwaye indawo yokubila ngama-3500 ℃.
Indlela yokuphucula i-cerium oxide
Ubulukhuni bee-CEO2 amasuntswana ayiphezulu. Njengoko kubonisiwe kwitheyibhile engezantsi, ubushushu be-cerium oxide bungaphantsi kakhulu kune-dayimani kunye ne-almininugo oxide, kwaye iphantsi kwe-ziirconsium oxide kunye ne-ferric oxide. Ayisiyonto ingekho mchwephesha kwi-Deposh Izixhobo ezisekwe kwi-Asicton Asside Oxidee, njengeglasi ye-Silicate, iglasi ye-quartz, njl njl, njl njl. Nangona kunjalo, i-cerium oxide okwangoku ingumgubo owuthandayo we-pillen ye-Poling Slicton Asside Izixhobo okanye i-Silicon Nitride. Ingabonwa ukuba i-cerium ye-cerium oxiasium oxide ikwanayo nezinye iziphumo ngaphandle kweziphumo zonxibelelwano. Ubulukhuni bedayimani, esisetyenziselwa ukugaya i-digiting kunye nezinto zokwakha, zihlala zinezithuba zeoksijin kwi-CEO2 LATE, ezitshintsha iipropathi zekhemikhali kwaye zinefuthe elithile kwiipropathi zokuposa. I-cerium esetyenziswayo i-cerium ye-cerium ye-cerium oxide inesixa esithile somnye omnye onqabileyo we-oxide. I-PraseodMummium Oxide (PR6O11) ikwanobuso obugxile kubuso be-cuic lateres, elungele ukudiliza, ngelixa elinye i-lanthanade yoMhlaba onqabileyo alinamandla e-oxidey. Ngaphandle kokutshintsha isakhiwo sekristali ye-CEO2, inokwenza isisombululo esomeleleyo kunye noluhlu oluthile. Kwisithuba esiphakamileyo se-Nano-Cerium Oxide i-Polled Polder (VK-vk-vk-ch. Xa i-chectilic cheliling, kuyacetyiswa ukuba isebenzise i-cerium ye-cerium ecocekileyo ye-cideal oxide (VK-CE-CE-CEC01).
Ukusetyenziswa kwe-cierium oxide i-powder yokwakha
I-cerium oxide powder ipoller (VK-vk-ch01), ikakhulu isetyenziselwa iimveliso zeglasi yePolish, isetyenziswa ikakhulu kule mimandla ilandelayo:
I-1. Iiglasi, iilebhu zeglasi zipholileyo;
2. Iilensi zokukhetha, iglasi yokuphuma, iilensi, njl njl.;
3. Iglasi yeselfowuni yeselfowuni, umphezulu we-Watch (umnyango wokubukela), njl.;
I-4. I-LCD ibeka esweni zonke iintlobo zescreen se-LCD;
I-5. Iidayimani ezishushu (iidayimani ezishushu (amakhadi, iidayimani kwi-jean), iibhola ezikhanyayo (i-chandeline yexabiso le-plandelier kwiholo enkulu);
6. Iingcibi zekristali;
I-7. Ukufakwa kwenxalenye ye-jade
I-cerivating ye-cierium ye-ciesium ye-cieal
Umphezulu we-cerium oxide upatshwe nge-aluminium ukuba iphucule i-pillen yeglasi yeglasi.
UPhando lweTekhnoloji kunye noPhuhliso lweSebe leMfundo le-Urbasine. Inqunyelwe, ecetyelwe ukuba ukuguqulwa komhlaba kunye nokuguqulwa komhlaba kwamasuntswana okuphumeza zezona ndlela ziphambili kunye neendlela zokuphucula ukusebenza nokuchaneka kwe-CMP Polling. Ngenxa yokuba iipropathi zesuntswana zinokuqulwaliswa kukudityaniswa kwezinto ezahlukeneyo, kunye nozinzo zokusasazwa kunye nokusebenza ngokuphuculwa kwe-pile yokuphucula i-pingry kungaphuculwa ngokuguqulwa komhlaba. Ukulungiswa kwenkqubo kunye nokusebenza kwe-cealing ye-CEO2 i-tio2 inokuphucula ukusebenza nge-pio2 ingaphezulu kwe-50%, kwaye kwangaxeshanye, iziphene ezingaphezulu komhlaba zincitshisiwe ngama-80%. Isiphumo sokulinganisa i-cea2 zro2 kunye neSio2 2ceo2 ye-oxilayo Ke ngoko, itekhnoloji yokulungiselela iCope-I-Cocimite Occial Occides ibaluleke kakhulu kuphuhliso lwezixhobo ezintsha zokuphumeza kunye nengxoxo yendlela yokuphucula. Ukongeza kwixabiso lokudla, urhulumente kunye nokusasazwa kwe-dopant kumasuntswana adityanisiweyo kuchaphazela kakhulu iipropathi zawo zomhlaba kunye nokusebenza kwamapoli.
Phakathi kwazo, i-synthesis yamasuntswana ePoliking enemigangatho yokuvala inomtsalane ngakumbi. Ke ngoko, ukukhetha iindlela zokwenziwa kunye neemeko zibaluleke kakhulu, ngakumbi ezo ngeendlela ezilula nezinendleko. Usebenzisa i-Hydium Carbonate njengeyona nto iphambili eluhlaza, i-aluminium-doped cerium oxide amasuntswana e-Polia edityanisiweyo ye-mechanochemical yendlela. Phantsi kwesenzo samandla omatshini, amasuntswana amakhulu e-Hirium Carbonate anokucocwa kumasuntswana amahle, ngelixa i-Alumnum ye-Alumnum ye-Alumniam nge-Ammonia amanzi kwi-Amoridas Coltoidas Amanzi. Amasuntswana e-colloidal aqhotyoshelwe ngokulula kumasuntswana e-ciebonate, kwaye emva kokomile kwaye alawule, i-aluminium inokuthi ifezekiswe kumphezulu we-cirium oxide. Le ndlela yayisetyenziselwa ukuqesha amasuntswana e-cerium oxinaniselwano ngexabiso le-Aluminium Dos, kwaye intsebenzo yabo yePolish yaphawulwa. Emva kwenani elifanelekileyo le-aluminium yongezwa kumphezulu wesuntswana ye-cerium ox, ixabiso elibi lokukhula komgangatho luya kunyuka, ngaloo nto lenza umsantsa phakathi kwamasuntswana aphantsi. Kukho ukurhoxiswa kwe-electrostatic, nto leyo ikhuthaza ukuphucuka kokuzinquma okuphefumlayo. Kwangelo xesha, i-adsound yoqoqosho phakathi kwamasuntswana athambileyo kunye ne-sulting ethambileyo nge-colomb yomtsalane iya komelezwa, kwaye inyanzelise ukunxibelelana kweglasi ye-arasive, kwaye ikhuthaza ukuphuculwa kwenqanaba lokuphumelela.
