Cov ncauj lus kom ntxaws thiab cov ntawv thov
Ceeline yog cov tshuaj lom neeg lub cim nrog lub cim CE thiab atomic naj npawb 58. Nws yog cov neeg muaj ntau ntau thiab ntau siv ntawm lub ntiaj teb tsis tshua muaj.
Khoom: Cerium yog qhov muag muag, silvery, thiab malleable cov hlau uas yog cov tshuaj tiv thaiv heev thiab yooj yim oxidizes hauv huab cua. Nws muaj qhov tseem ceeb melting point thiab yog ib tus neeg saib xyuas zoo ntawm hluav taws xob. Cerium tseem muaj lub peev xwm paub txog nws qhov kev zam tshwj xeeb kom yauv hloov pauv ntawm nws lub xeev oxidation, uas ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov.
Cov Ntawv Thov:Cerium siv tau ntau yam kev lag luam ntawm kev lag luam vim nws cov khoom tshwj xeeb. Qee daim ntawv thov tseem ceeb muaj xws li:
1.Catalysts:Creium ox oxide feem ntau yog siv los ua catalyst nyob rau hauv ntau cov txheej txheem tshuaj lom neeg, xws li automotive catalalytic conveytic, muaj kuab paug ntxaij tswj, thiab roj hlwb. Nws pab rau kev txhawb kev zoo dua kev sib txuas lus thiab txo cov pa phem txo kev phom sij
2.Iav thiab Polishing:Creium oxide yog qhov dav nyob rau hauv cov iav tsim khoom, tshwj xeeb tshaj yog rau cov iav polishing. Nws yog ntxiv rau iav cov qauv tsim los txhim kho nws cov khoom kho kho tshiab, ua kom cov index tsis tuaj yeem, thiab kos tsis kam. Nws tseem siv nyob rau hauv kev tsim cov khoom tsim kho kom zoo, tsom iav, thiab lo ntsiab muag
3.Ceramics:Cerium tebchaw yog siv nyob rau hauv kev tsim cov ntaub ntawv ceramic. Lawv muaj kev txhim kho lub zog, ua kom ruaj khov, thiab cua sov ua rau muaj txiaj ntsig zoo li cov khoom siv ceramic, lub txim roj hlwb
4.Hlau alloys:Cerium yog siv los ua ib qho kev sib txuam ua ke hauv kev tsim cov alloys tshwj xeeb, xws li cov alloys muaj ntau yam. Cov alloy nthuav tawm cov khoom txhim kho txhim kho cov khoom zoo li nce lub zog, txo cov nplaim taws, thiab nce siab ruaj khov, thiab nce siab ruaj khov
5.Hydrogen Cia:Cerium tebchaw muaj peev xwm nqus tau thiab tso hydrogen ntawm qhov kub muaj zog. Cov cuab yeej no tau coj mus tshawb nrhiav thiab kev txhim kho cov khoom siv cerium-borium rau cov ntawv thov hydrogen cia.
6.Chiv:Cerium tebchaw, xws li cerium sulfate, yog siv hauv kev ua liaj ua teb ua chiv. Lawv pab nyob rau hauv cov qoob loo cog qoob loo yields, txhim kho cov av zoo, thiab txo cov khoom noj muaj txiaj ntsig zoo.
Kev Nyab Xeeb: Thaum Careium feem ntau suav tias muaj kev nyab xeeb, nws cov lus teb yuav tsum tau ua kom zoo. Qee qhov cerium sib txuas ua tuaj yeem yog tshuaj lom thiab yuav ua rau muaj kev cuam tshuam lossis tsis paub txog qhov sib tiv tauj. Yuav tsum tau ua kom muaj kev nyab xeeb kom muaj kev nyab xeeb kom muaj kev nyab xeeb yuav tsum tau ua thaum ua haujlwm nrog cerium.
Hauv kev xaus, cerium yog ib qho txiaj ntsig thiab cov khoom tseem ceeb nrog ntau cov kev siv hauv catalysts, ceramics, hydrogen cia, thiab kev ua liaj ua teb. Nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv ntau yam lag luam, ua rau thev naus laus zis thiab ib puag ncig kev ruaj khov.
