Tshawb hauv cov khoom ntoo barium

Qiayog ib qho tseem ceeb ntawm cov khoom lag luam hlau nrog ntau yam khoom thiab cov ntawv thov. Peb yuav ua kom tob tob ntawm kev paub yooj yim ntawmqia, suav nrog nws nomenclature, cov qauv, tshuaj lom neeg cov khoom, thiab kev siv hauv ntau thaj teb. Cia peb tshawb nrhiav lub ntiaj teb no zoo kawg nkaus ntawm cov hlau ua ke! Barium nomrlature thiab cov qauv barium (BA) yog ib qho kev hloov tsheb hlau nyob rau lub sijhawm 4 thiab pab pawg 5 ntawm lub rooj ntu. Nws tus lej atomic yog 56, thiab nws cov kev teeb tsa hluav taws xob yog [AR] 3d10 4s1. Muaj peb isotopes ntawm barium: ba-110, ba-122, thiab ba-137. BA-137 yog qhov ruaj khov tshaj plaws isotope, suav rau 99.8% ntawm lub ntiaj teb cov cua. Barium tshuaj tshuaj tiv thaiv budageries Barium muaj ntau yam tshuaj, ua rau nws lub ntsiab lus tseem ceeb hauv ntau yam tshuaj lom neeg tseem ceeb.

Nov yog qee qhov ntawm cov khoom muaj nqis:

1. Zoo hluav taws xob conductivity: Barium hlauYog tus saib xyuas hluav taws xob zoo, yog li nws tau siv dav siv raws li cov khoom siv ua haujlwm hauv kev lag luam hluav taws xob.

2. Siab Melting point: Barium muaj qhov taw qhia zoo heev ntawm 3820 ° C (txawm nyob ntawm tus qauv ntsuas huab cua siab), uas ua rau nws ruaj khov nyob rau ntawm qhov kub.

3. Zoo corrosion tsis kam: Barium qhia tau zoo corrosion tsis kam nyob rau hauv feem ntau acids thiab alkalis, yog li nws feem ntau siv los ua cov khoom siv tiv thaiv xeb.

4. Zoo Magnetism: Txawm hais tias barium yog cov khoom siv ferromagnetic, nws sib nqus tau zoo heev yog tsawg heev, yog li nws muaj cov khoom sib nqus ntawm cov khoom sib nqus. Cov chaw thov ntawm Barium

Vim yog cov khoom tshwj xeeb ntawm Barium, nws muaj ntau cov kev siv hauv ntau thaj teb. Cov hauv qab no yog qee qhov tseem ceebChaw Thov:

1.Kev lag luam hluav taws xob: Barium yog tsuas yog siv los tsim cov hluav taws xob Cheebtsam xws li cov khoom siv hluav taws xob thiab cov cab hluav taws xob hluav taws xob thiab cov cab hluav taws xob hluav taws xob ntau zaus.

2.Kev lag luam iav: Barium yog siv los ua ntxiv rau hauv iav ntau lawm los txhim kho lub hardness, khawb tiv thaiv thiab kub ua kom tsis taus ntawm iav.

3.Kev Lag Luam Metallurgical:QiaYuav siv tau los rho tawm cov ntsiab lus tseem ceeb los ntawm lwm cov hlau ores, xws li tooj liab, txhuas thiab zinc.

4.Kev lag luam tshuaj: Barium tuaj yeem siv los tsim cov hluavtaws roj hmab, plastics thiab lwm yam khoom siv tshuaj lom.

5.Kev tiv thaiv ib puag ncig: Barium tuaj yeem siv los ua tus neeg saib xyuas dej kom tshem tawm cov hlau hnyav thiab lwm yam khoom muaj teeb meem hauv dej.
