Cerium, lub npe los ntawm lus Askiv lub npe ntawm lub hnub qub Ceres.Cov ntsiab lus ntawm cerium nyob rau hauv lub ntiaj teb crust yog hais txog 0.0046%, uas yog cov feem ntau ntau hom ntawm lub ntiaj teb tsis tshua muaj ntsiab.Cerium feem ntau muaj nyob rau hauv monazite thiab bastnaesite, tab sis kuj nyob rau hauv cov khoom fission ntawm uranium, thorium, thiab plutonium.Nws yog ib qho ntawm cov kev tshawb fawb hotspots hauv physics thiab cov ntaub ntawv science.
Raws li cov ntaub ntawv muaj, cerium yog inseparable nyob rau hauv yuav luag tag nrho cov tsawg ntiaj teb daim ntawv thov teb.Nws tuaj yeem piav qhia tias yog "nplua nuj thiab zoo nraug" ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb thiab txhua yam "tus kws kho mob cerium" hauv daim ntawv thov.
Cerium oxide tuaj yeem siv ncaj qha los ua hmoov polishing, roj additive, roj av catalyst, pa roj purifier txhawb nqa, thiab lwm yam. Nws kuj tseem siv tau los ua cov khoom siv hauv hydrogen cia cov ntaub ntawv, cov khoom siv thermoelectric, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium. silicon carbide abrasives, roj cell raw cov ntaub ntawv, cov ntaub ntawv hlau nplaum ruaj khov, txheej, tshuaj pleev ib ce, roj hmab, ntau yam hlau alloy, lasers thiab Non-ferrous hlau, thiab lwm yam.
Nyob rau hauv xyoo tas los no, high-purity cerium oxide cov khoom tau siv rau cov txheej ntawm chips thiab polishing ntawm wafers, semiconductor cov ntaub ntawv, thiab lwm yam .;high-purity cerium oxide yog siv nyob rau hauv tshiab nyias zaj duab xis kua siv lead ua zaub (LFT-LED) additives, polishing agents, thiab circuit corrosives;High purity Cerium carbonate yog siv los tsim high-purity polishing hmoov rau polishing circuits, thiab high-purity cerium ammonium nitrate yog siv los ua ib tug corrosive tus neeg saib xyuas rau Circuit Court boards thiab ib tug sterilization thiab preservative rau haus.
Cerium sulfide tuaj yeem hloov cov hlau lead, cadmium thiab lwm yam hlau uas tsim kev puas tsuaj rau ib puag ncig thiab tib neeg thiab siv rau hauv pigments.Nws tuaj yeem ua xim yas thiab tuaj yeem siv rau hauv cov xim, number case, thiab ntawv industries.
Lub Ce:LiSAF laser system yog ib lub xeev ruaj khov laser tsim los ntawm Tebchaws Meskas.Nws tuaj yeem siv los txheeb xyuas cov riam phom lom neeg los ntawm kev saib xyuas cov concentration ntawm tryptophan, thiab nws kuj tuaj yeem siv rau hauv cov tshuaj.
Daim ntawv thov ntawm cerium rau iav yog ntau haiv neeg thiab ntau yam.
Cerium oxide yog ntxiv rau iav niaj hnub, xws li cov iav vaj tsev thiab tsheb, iav siv lead ua, uas tuaj yeem txo qhov kev xa tawm ntawm cov hluav taws xob ultraviolet, thiab tau siv dav hauv Nyiv thiab Tebchaws Meskas.
Cerium oxide thiab neodymium oxide yog siv rau iav decolorization, hloov cov tsoos dawb arsenic decolorizing tus neeg saib xyuas, uas tsis tsuas yog txhim kho cov efficiency, tab sis kuj zam cov pa phem ntawm dawb arsenic.
Cerium oxide kuj yog ib qho tshuaj pleev xim iav zoo heev.Thaum lub iav pob tshab nrog lub ntiaj teb tsis tshua muaj xim tus neeg saib xyuas absorbs pom lub teeb nrog lub wavelength ntawm 400 txog 700 nanometers, nws nthuav tawm xim zoo nkauj.Cov tsom iav muaj xim no tuaj yeem siv los ua teeb pom kev dav hlau rau kev dav hlau, kev tsav tsheb, ntau lub tsheb, thiab ntau yam kev kos duab zoo nkauj.Kev sib xyaw ua ke ntawm cerium oxide thiab titanium dioxide tuaj yeem ua rau lub khob pom daj.
Cerium oxide hloov cov tshuaj arsenic oxide ib txwm ua rau iav fining tus neeg saib xyuas, uas tuaj yeem tshem tawm cov npuas thiab cov xim xim.Nws muaj cov txiaj ntsig tseem ceeb hauv kev npaj cov iav tsis muaj xim.Cov khoom tiav lawm muaj lub ci dawb, zoo pob tshab, txhim kho iav lub zog thiab kub tsis kam, thiab tib lub sijhawm tshem tawm cov pa phem ntawm arsenic rau ib puag ncig thiab iav.
Tsis tas li ntawd, nws yuav siv sij hawm 30-60 feeb los polish lub lens nrog cerium oxide polishing hmoov hauv ib feeb.Yog tias siv hlau oxide polishing hmoov, nws yuav siv sij hawm 30-60 feeb.Cerium oxide polishing hmoov muaj qhov zoo ntawm kev siv me me, ceev polishing ceev thiab siab polishing efficiency, thiab tuaj yeem hloov polishing zoo thiab ua haujlwm ib puag ncig.Nws yog dav siv nyob rau hauv polishing ntawm lub koob yees duab, lub koob yees duab lo ntsiab muag, TV duab raj, spectacle lo ntsiab muag, thiab lwm yam.
