Daim ntawv thov ntawm cerium dioxide / CeO2 nanoparticle:

(1) Ceric dioxide nanopowder rau polishing: Nano cerium oxide yog tam sim no feem ntau siv abrasive rau iav polishing.Nws yog dav siv nyob rau hauv precision ua ntawm iav thiab kho qhov muag Cheebtsam thiab tau kawm ntau yam.Dab tsi cuam tshuam cov nyhuv polishing hauv cov hmoov polishing yog qhov loj me, purity thiab hardness ntawm CeO2.Qhov loj me me yog qhov tseem ceeb.Qhov loj me me yog tsim rau polishing ntawm cov khoom siv kho qhov muag zoo tib yam thiab cov tsom iav lo ntsiab muag, thaum qhov me me me me yog tsim rau cov kev kub ceev polishing ntawm cov lo ntsiab muag zoo.

Piv txwv li: Raws li cov khoom siv ntau tshaj plaws thiab yooj yim inorganic, iav yog dav siv nyob rau hauv cov cwj mem-notebook computer hard disk iav substrates, cov koob yees duab chips, ultra-precision optical lo ntsiab muag, optical qhov rais thiab lwm yam kho qhov muag Cheebtsam, raws li zoo raws li optical kev sib txuas lus Cheebtsam, flat-panel zaub thiab lwm yam khoom siv hluav taws xob siab heev.Ultra-smooth, sub-nanometer roughness, tiaj tus iav nto tsis muaj qhov tsis xws luag tau dhau los ua qhov tseem ceeb cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv high-tech.Chemical mechanical polishing (CMP) yog ib feem tseem ceeb ntawm kev ua silicon wafer thiab tag nrho cov txheej txheem tso thiab etching hauv kev tsim cov khoom sib xyaw ua ke.Nws siv lub tshuab polishing nyhuv ntawm ultrafine abrasive hais nyob rau hauv CMP slurry thiab tshuaj corrosion nyhuv ntawm slurry.Lub optical disc tsim ib qho chaw tiaj tus ntawm silicon wafer uas tau ua cov qauv Circuit Court.Tam sim no nws yog ib lub tshuab tshiab uas tuaj yeem muab lub ntiaj teb flattening hauv kev tsim cov txheej txheem ntawm VLSI circuits.

(2) Nano-cerium dioxide siv rau catalyst muaj kev ua tau zoo redox.Cerium oxide nanopowder tsis tsuas yog muaj cov pa oxygen cia thiab tso pa tawm ua haujlwm xwb, tab sis kuj yog cov oxide catalyst tshaj plaws hauv lub ntiaj teb tsis tshua muaj oxide series.Yog li ntawd, nano ceria tuaj yeem siv los ua tus neeg sawv cev pabcuam los txhim kho cov catalytic kev ua tau zoo ntawm cov catalyst hauv ntau zaus.

(3) Ceric oxide nano particle siv hauv kev lag luam steel: Siv nano-cerium oxide ua txheej thiab cov khoom ntxiv tuaj yeem txhim kho oxidation tsis kam, kub corrosion, dej corrosion thiab vulcanization zog ntawm high-temperature alloys thiab stainless hlau, thiab kuj tuaj yeem ua tau. siv los ua ib qho inoculant rau ductile hlau.

(4) Cerium oxide nano hmoov tuaj yeem siv rau hauv cov khoom siv ultraviolet absorbing vim nano CeO2 muaj ntau cov hluav taws xob hloov hluav taws xob ntau ntau, zoo heev optical rhiab heev rau ultraviolet lub teeb nqus.Ua ke nrog cov nyhuv me me, cov nyhuv tshwj xeeb ntawm qhov chaw, thiab cov nyhuv macroscopic quantum ntawm nanoparticle, CeO2 nano muaj zog tawg thiab cuam tshuam los ntawm ultraviolet lub teeb.Ntxiv mus, CeO2 muaj kev ruaj ntseg zoo, kev nyab xeeb thiab tsis muaj tshuaj lom, muaj peev txheej ntau, thiab tus nqi npaj qis, yog li nws xav tias yuav dhau los ua hom tshiab ntawm ultraviolet absorber siv hauv ntau yam.
