Daim ntawv thov

Catalysts hauv kev lag luam automotive: Cerium yog dav siv nyob rau hauv catalytic converters los txo cov teeb meem emissions los ntawm combustion engines. Nws pab nyob rau hauv oxidation ntawm carbon monoxide thiab hydrocarbons, yog li ua rau tag nrho cov efficiency ntawm lub tsheb lub tso pa system. Cerium lub peev xwm khaws cia thiab tso tawm cov pa oxygen ua rau nws yog ib qho tseem ceeb hauv peb txoj kev catalysts uas pab ua kom huab cua huv.
Iav thiab Ceramics: Cerium dioxide yog cov khoom tseem ceeb hauv kev tsim cov iav thiab ceramics. Nws ua raws li tus neeg saib xyuas polishing, muab qhov zoo tshaj plaws rau cov iav nto. Tsis tas li ntawd, cerium tebchaw yog siv los txhim kho cov khoom kho qhov muag ntawm iav, ua kom nws tiv taus UV hluav taws xob ntau dua thiab ua kom nws ruaj khov. Daim ntawv thov no tseem ceeb tshwj xeeb hauv kev tsim cov khoom siv iav siab xws li lo ntsiab muag thiab cov lus qhia.
Alloying Additive: Cerium yog siv los ua tus neeg sawv cev alloying rau ntau yam hlau, suav nrog txhuas thiab hlau. Qhov sib ntxiv ntawm cerium txhim kho cov khoom siv ntawm cov alloys, xws li lub zog, ductility, thiab oxidation kuj. Cerium-muaj alloys yog siv nyob rau hauv aerospace, tsheb, thiab kev tsim kho daim ntawv thov uas txhim khu kev qha thiab durability yog ib qho tseem ceeb.
Phosphors nyob rau hauv cov teeb pom kev zoo thiab tso saib: Cerium yog ib qho tseem ceeb ntawm phosphor cov ntaub ntawv siv nyob rau hauv fluorescent teeb thiab LED teeb pom kev zoo. Nws pab hloov lub teeb ultraviolet mus rau hauv lub teeb pom kev, txhim kho kev ua haujlwm thiab xim zoo ntawm lub teeb tawm. Tsis tas li ntawd, cov ntaub ntawv cerium-doped kuj tau siv rau hauv cov khoom siv thev naus laus zis xws li TVs thiab khoos phis tawj cov ntxaij vab tshaus los txhim kho cov xim luam tawm thiab ci ntsa iab.
