Daim ntawv thov

Catalysts hauv kev lag luam automotive: Cerium tau siv dav hauv catalytic cov hloov hloov los txo cov kev tiv thaiv kev tsim txom los ntawm sab hauv kev siv hluav taws xob sab hauv. Nws pab hauv oxidation ntawm carbon monoxide thiab hydrocarbons, yog li nce cov kev ua haujlwm ntawm lub tsheb tso tawm. Cerium lub peev xwm khaws cia thiab tso cov oxygen ua rau nws yog qhov tseem ceeb hauv peb-txoj kev catalysts uas pab ntxuav cua.
Iav thiab Ceramics: Cerium dioxide yog cov khoom tseem ceeb hauv kev tsim cov iav thiab khoom sib xyaw. Nws ua raws li tus neeg sawv cev ua polishing, muab kev ua tiav zoo rau lub iav saum npoo. Ib qho ntxiv, cerium tebchaw yog siv los txhim kho lub thaj chaw kho qhov muag ntawm iav, ua rau nws tiv taus UV hluav taws xob thiab nce nws lub siab. Daim ntawv thov no yog qhov tshwj xeeb tshaj nyob rau hauv kev tsim cov high-end iav cov khoom lag luam xws li lo ntsiab muag thiab cov lus ci thiab cov lus qhia.
Alloying additive: Cerium yog siv los ua ib qho kev ua kom zoo rau cov tshuaj tiv thaiv ntau yam, suav nrog txhuas thiab hlau. Qhov kev sib ntxiv ntawm cerium txhim kho cov khoom siv ntawm cov alloys, xws li muaj zog, ductility, thiab oxidation tsis kam. Cerium-muaj cov alloys tau siv hauv aerospace, tsheb, thiab kev siv tsheb ua haujlwm uas txhim kho kev ua tau zoo thiab ua rau muaj txiaj ntsig yog qhov tseem ceeb.
Phosphors hauv teeb pom kev zoo thiab qhia tawm: Cerium yog qhov tseem ceeb ntawm phosphor cov ntaub ntawv siv hauv cov roj fluorescent thiab coj teeb pom kev zoo. Nws pab hloov hloov lub teeb Ultraviolet rau hauv pom lub teeb pom kev, txhim kho qhov ua tau zoo thiab cov xim zoo ntawm lub teeb pom kev. Ib qho ntxiv, cerium-doped cov ntaub ntawv kuj tau siv nyob rau hauv cov cuab yeej thev naus laus zis xws li TVs thiab cov ntxaij vab tshaus thiab cov khoos phis tawj los txhim kho cov xim me ntsis thiab ci.
