Cerium oxide, kuj hu uacerium dioxide, muaj cov qauv molecularCeO 2. Nws tuaj yeem siv los ua cov khoom siv polishing, catalysts, UV absorbers, roj cell electrolytes, automotive tso absorbers, hluav taws xob ceramics, thiab lwm yam.
Daim ntawv thov zaum kawg xyoo 2022: MIT engineers siv cov ceramics los ua cov roj nplaum nplaum rau lub zog cog khoom hauv lub cev. Cov electrolyte ntawm cov roj nplaum nplaum no yog ua los ntawm cerium dioxide, uas muaj ion conductivity siab thiab txhua yam muaj zog thiab yog dav siv los ua electrolyte rau hydrogen roj hlwb. Cerium dioxide kuj tau raug pov thawj tias yog biocompatible
Tsis tas li ntawd, lub zej zog kev tshawb fawb txog qog noj ntshav tau nquag kawm txog cerium dioxide, uas zoo ib yam li zirconia siv hauv kev cog hniav thiab muaj biocompatibility thiab kev nyab xeeb.
· Tsis tshua muaj lub ntiaj teb polishing nyhuv
Tsis tshua muaj lub ntiaj teb polishing hmoov muaj qhov zoo ntawm kev ceev polishing ceev, siab smoothness, thiab kev pab lub neej ntev. Piv nrog cov tsoos polishing hmoov - hlau liab hmoov, nws tsis ua phem rau ib puag ncig thiab yooj yim tshem tawm los ntawm cov khoom siv adhered. Polishing lub lens nrog cerium oxide polishing hmoov yuav siv sij hawm ib feeb kom tiav, thaum siv hlau oxide polishing hmoov yuav siv sij hawm 30-60 feeb. Yog li ntawd, tsis tshua muaj lub ntiaj teb polishing hmoov muaj qhov zoo ntawm qhov tsawg npaum li cas, ceev polishing ceev, thiab siab polishing efficiency. Thiab nws tuaj yeem hloov qhov polishing zoo thiab kev ua haujlwm ib puag ncig.
Nws yog advisable siv high cerium polishing hmoov rau optical lo ntsiab muag, thiab lwm yam; Tsawg cerium polishing hmoov yog dav siv rau iav polishing ntawm cov iav tiaj tus, daim duab raj iav, iav, thiab lwm yam.
· Daim ntawv thov ntawm catalysts
Cerium dioxide tsis tsuas yog muaj cov pa oxygen cia thiab tso tawm haujlwm xwb, tab sis kuj yog cov oxide catalyst tshaj plaws nyob rau hauv lub ntiaj teb tsis tshua muaj oxide series. Electrodes ua lub luag haujlwm tseem ceeb hauv cov tshuaj electrochemical ntawm cov roj hlwb. Electrodes tsis yog tsuas yog ib qho tseem ceeb thiab tseem ceeb ntawm cov roj hlwb, tab sis kuj yog cov catalysts rau cov tshuaj tiv thaiv electrochemical. Yog li ntawd, nyob rau hauv ntau lub sij hawm, cerium dioxide yuav siv tau raws li ib tug additive los txhim kho cov catalytic kev ua tau zoo ntawm catalyst.
· Siv rau cov khoom nqus UV
Hauv cov tshuaj pleev ib ce high-end, nano CeO2 thiab SiO2 nto coated composites yog siv los ua cov ntaub ntawv tseem ceeb ntawm UV absorbing los kov yeej cov teeb meem ntawm TiO2 los yog ZnO uas muaj xim daj ntseg thiab tsis tshua muaj UV nqus.
Ntxiv nrog rau kev siv tshuaj pleev ib ce, nano CeO2 kuj tseem tuaj yeem ntxiv rau cov polymers los npaj UV resistant aging fibers, uas ua rau cov tshuaj fiber ntau fabrics nrog zoo heev UV thiab thermal radiation shielding nqi. Qhov kev ua tau zoo tshaj qhov tam sim no siv TiO2, ZnO, thiab SiO2. Tsis tas li ntawd, nano CeO2 kuj tuaj yeem muab ntxiv rau cov txheej txheem los tiv thaiv ultraviolet hluav taws xob thiab txo cov laus thiab degradation tus nqi ntawm polymers.
