Bariumyog hlau hnyav. Cov hlau hnyav xa mus rau cov hlau uas muaj lub ntiajteb txawj nqus ntau dua 4 txog 5, thaum barium muaj qhov sib nqus ntawm 7 lossis 8, yog li barium yog cov hlau hnyav. Barium tebchaw yog siv los tsim ntsuab nyob rau hauv foob pob hluav taws, thiab hlau barium yuav siv tau raws li ib tug degassing tus neeg saib xyuas kom tshem tawm cov kab gases los ntawm lub tshuab nqus tsev raj thiab cathode ray raj, nrog rau ib tug degassing tus neeg saib xyuas rau refining hlau.
Puas yog barium yog hlau hnyav?
Barium yog hlau hnyav.
Yog vim li cas: Cov hlau hnyav yog hais txog cov hlau uas muaj lub ntiajteb txawj nqus ntau dua 4 txog 5, thaum barium muaj ib qho kev nqus ntawm 7 lossis 8, yog li barium yog cov hlau hnyav.
Taw qhia rau Barium: Barium yog ib qho tseem ceeb hauv alkaline ntiaj teb hlau, mos alkaline ntiaj teb hlau nrog ib tug silver dawb luster. Cov khoom siv tshuaj muaj zog heev, thiab barium elemental yeej tsis tau pom nyob rau hauv qhov xwm txheej. Cov minerals ntau tshaj plaws ntawm barium nyob rau hauv cov xwm yog barium sulfate thiab barium carbonate, ob qho tib si uas yog insoluble nyob rau hauv dej.
Kev siv barium: Barium compounds yog siv los tsim ntsuab hauv cov foob pob hluav taws, thiabbarium hlautuaj yeem siv los ua tus neeg saib xyuas degassing kom tshem tawm cov kab hluav taws xob los ntawm lub tshuab nqus tsev thiab cov kab hluav taws xob cathode, nrog rau tus neeg saib xyuas degassing rau refining hlau.
Kev siv barium yog dab tsi?
Barium yog cov khoom siv tshuaj nrog cov cim tshuaj Ba.
Barium muaj ntau yam kev siv, qee qhov yog:
1 Barium compounds yog siv los ua raw khoom thiab additives hauv kev lag luam. Piv txwv li, barium compounds tuaj yeem siv los tsim cov teeb pom kev zoo phosphors, nplaim hluav taws xob, cov khoom siv ntxiv, thiab cov catalysts.
2. Barium tuaj yeem siv los tsim cov raj X-ray thiab siv dav hauv kev kho mob thiab kev lag luam. X-ray raj yog ib qho cuab yeej uas tsim cov X-rays rau kev kuaj mob thiab kuaj cov ntawv thov.
3, Barium lead iav yog cov khoom siv kho qhov muag iav uas nquag siv, feem ntau siv los tsim cov khoom siv kho qhov muag, tsom iav, thiab cov tsom iav tsom iav.
4, Barium yog siv los ua cov khoom siv ntxiv thiab cov khoom siv hlau hauv kev tsim roj teeb. Nws tuaj yeem txhim kho kev ua haujlwm thiab lub zog cia ntawm cov roj teeb.
5. Barium compounds kuj tseem siv los tsim cov khoom xws li tshuaj tua kab, ceramics, thiab cov ntaub nplaum sib nqus. Barium tebchaw kuj tseem siv tau los tswj cov kab tsuag thiab nroj tsuag hauv cov nyom thiab orchards.
Thov nco ntsoov tias barium yog ib qho tshuaj lom, yog li yuav tsum tau ceev faj thaum siv thiab tuav cov khoom sib txuas barium, thiab cov kev ntsuas kev nyab xeeb thiab kev ua kom ruaj khov yuav tsum tau ua raws.
Cov yam ntxwv ntawm barium
Barium yog cov khoom siv hlau, nyiaj dawb hauv cov xim, nrog cov nplaim daj ntsuab thaum hlawv. Barium ntsev yog siv los ua cov xim dawb siab heev. Barium hlau yog ib qho zoo heev deoxidizer rau tooj liab refining: ib txoj kev kuaj mob rau tej yam kab mob ntawm txoj hlab pas thiab plab hnyuv kab mob, qhov chaw uas cov neeg mob noj barium sulfate thiab undergo X-ray fluoroscopy los yog imaging. Me ntsis glossy, nrog extensibility. Qhov ceev 3. 51 grams ib cubic centimeter. Melting point 725 ℃. Kub taw tes 1640 ℃. Valence + 2. Ionization zog 5. 212 electron volts. Cov khoom siv tshuaj muaj zog heev thiab tuaj yeem hnov mob nrog rau feem ntau tsis yog hlau. Thaum kub kub thiab nyob rau hauv cov pa oxygen, barium peroxide yog generated. Yooj yim rau oxidize, muaj peev xwm ntawm reacting nrog dej los tsim hydroxides thiab hydrogen; Dissolve nyob rau hauv acid thiab tsim ntsev. Barium ntsev yog tshuaj lom tsuas yog barium sulfate. Qhov kev txiav txim ntawm cov hlau ua haujlwm yog nruab nrab ntawm cov poov tshuaj thiab sodium.
