Lub hauv paus rau phau ntawv
Cov ntsiab lus ntawmqiaNyob rau hauv lub ntiaj teb crust yog 0.05%. Cov minerals feem ntau hauv xwm yog barite (barium sulfate) thiab witherite (Barium carbonate). Barium yog dav siv nyob rau hauv electronics, ceramics, tshuaj, roj av thiab lwm thaj teb.

1.Kev Lag Luam Hluav Taws Xob
Ib qho ntawm cov tseem ceeb ntawm barium yog ua ib tug getter kom tshem tawm cov roj nkev ntawm lub tshuab nqus tsev thiab cov duab hlab. Nws yog siv nyob rau hauv lub xeev ntawm evaporative getter zaj duab xis, thiab nws txoj haujlwm yog los ua kom tiv thaiv cov pa roj hluav taws xob hauv ntau lub tshuab hluav taws xob los ntawm kev cuam tshuam nrog cov pa roj hluav taws xob thiab cov teeb meem tsis zoo.
Barium Aluminium Nickel Getter yog cov leeg eves, cov leeg roj av, cov leeg yas, hnub ci colleor leeg thiab lwm yam khoom siv. Qee cov duab raj siv nitrided Barium txhuas getters, uas tso tawm ntau npaum li cas ntawm cov nitrogen nyob rau hauv cov evaporative exutermic tshuaj tiv thaiv. Thaum muaj pes tsawg ntawm barium evaporates, vim yog lub ntsej muag nitrogen, tus geter npog ib ncig ntawm lub caj dab caj dab, uas tsis tsuas yog muaj qhov ci ci ntawm lub vijtsam.
2.Kev lag luam ceramic
Barium carbonate tuaj yeem siv cov pob txha ci ci. Thaum Barium Carbonate muaj nyob rau hauv lub ci ci, nws yuav tsim paj yeeb thiab ntshav.
Barium Titanate yog qhov yooj yim matrix raw khoom ntawm titanate series hauv cov captical ceramics thiab yog hu ua tus ncej ntawm lub cost ntawm lub tshuab hluav taws xob ceramics. Barium Titanate muaj siab Dielectric tas li, cov khoom siv hluav taws xob qis, tshwj xeeb siv nyob rau hauv cov khoom siv uas tsis muaj peev xwm, thiab siv hluav taws xob zoo tshaj plaws Nrhiav kom tau cov ntsiab lus, Crystal Ceramic Capacitors, Electro-optical zaub mov panels, cov ntaub ntawv cim xeeb, polymer-raws cov khoom thiab txheej txheem.
3.Qhov chaw kev lag luam
Barium salts (xws li barium nitrate) hlawv nrog xim ntsuab-daj thiab feem ntau siv los ua foob pob hluav taws thiab flares. Cov foob pob hluav taws dawb Peb pom qee zaum ua nrog cov roj ntoo barium oxide.
4.Nov extract
Baryte hmoov, tseem hu ua ntuj barium sulfate, yog tsuas yog siv los ua tus neeg sawv cev yuag rau cov roj thiab roj av. Ntxiv cov nyom mos txwv rau cov av nkos tuaj yeem nce cov av nkos ntawm cov av nkos nrog cov roj av hnyav, thiab yog li tiv thaiv tshuab hluav taws xob.
5.Pest tswj
Barium carbonate yog cov hmoov dawb uas yog insoluble hauv dej tab sis soluble hauv acid. Nws yog tshuaj lom thiab feem ntau siv ua cov nas tsuag lom. Barium carbonate tuaj yeem ua rau muaj kev cuam tshuam nrog cov kua roj plab hydrocoric kom tso cov tshuaj lom lom ions, ua rau cov tshuaj lom. Yog li ntawd, peb yuav tsum zam kev noj haus tsis zoo hauv lub neej txhua hnub.
6.Cedical Kev Lag Luam
Barium sulfate yog ntxhiab tsw ntxhiab thiab tsis muaj qab zib dawb uas yog tsis ua rau solub lossis kua qaub los yog alkali, yog li nws tsis tsim cov tshuaj lom ions. Nws yog feem ntau siv los ua cov tshuaj soj ntsuam kom xoo hluav taws xob rau kev kuaj ntshav, feem ntau hu ua "barium noj mov ua kom haum".
Cov kev kuaj hluav taws xob siv hluav taws xob siv barium tsuas yog vim tias nws tuaj yeem nqus tau x-rays hauv plab hnyuv kom nws loj hlob. Nws tsis muaj cov tshuaj uas muag hluav taws xob cuam tshuam nws tus kheej thiab yuav tau txiav tawm ntawm lub cev tom qab noj.
Cov ntawv thov no ua rau pom cov versatility ntawmbarium hlauThiab nws qhov tseem ceeb hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv hluav taws xob thiab kev lag luam siv tshuaj lom neeg. Lub cev siv tshuaj tshwj xeeb thiab tshuaj lom neeg ntawm Barium hlau ua nws ua si lub luag haujlwm tsis tseem ceeb hauv ntau qhov kev lag luam.
