Tshawb nrhiav lub caij Barium hlau

Bariumyog ib qho tseem ceeb ntawm cov hlau nrog ntau yam khoom tshwj xeeb thiab kev siv. Peb yuav ua tib zoo saib tob txog qhov kev paub ntawmbarium, suav nrog nws cov npe, qauv, tshuaj lom neeg, thiab kev siv hauv ntau yam. Cia peb tshawb nrhiav lub ntiaj teb zoo kawg nkaus ntawm cov hlau ua ke! Barium nomenclature thiab qauv Barium (Ba) yog ib qho kev hloov pauv hlau nyob rau hauv lub sij hawm 4 thiab pawg 5 ntawm lub sij hawm. Nws tus lej atomic yog 56, thiab nws cov qauv hluav taws xob yog [Ar] 3d10 4s1. Muaj peb lub isotopes ntawm barium: Ba-110, Ba-122, thiab Ba-137. Ba-137 yog cov isotope ruaj khov tshaj plaws, suav txog 99.8% ntawm lub ntiaj teb huab cua. Barium chemical zog Barium muaj ntau yam tshuaj lom neeg tshwj xeeb, ua rau nws yog lub hauv paus tseem ceeb hauv ntau yam tshuaj lom neeg tseem ceeb.

Nov yog qee cov khoom tsim nyog sau cia:

1. Zoo hluav taws xob conductivity: Barium hlauyog ib tug zoo hluav taws xob conductor, yog li nws yog dav siv los ua cov khoom siv hluav taws xob hauv kev lag luam hluav taws xob.

2. Siab melting point: Barium muaj qhov kub siab heev ntawm 3820 ° C (txawm tias nyob rau hauv cov txheej txheem atmospheric siab), uas ua rau nws ruaj khov ntawm qhov kub thiab txias.

3. Zoo corrosion kuj: Barium qhia tau hais tias zoo corrosion kuj nyob rau hauv feem ntau acids thiab alkalis, yog li nws yog feem ntau siv raws li ib tug anti-corrosion khoom.

4. Zoo hlau nplaum: Txawm hais tias barium yog cov khoom siv ferromagnetic, nws cov khoom siv hlau nplaum muaj tsawg heev, yog li nws muaj cov khoom sib nqus zoo. Kev siv thaj chaw ntawm barium

Vim muaj cov khoom tshwj xeeb ntawm barium, nws muaj ntau yam kev siv hauv ntau lub teb. Cov hauv qab no yog qee qhov tseem ceebKev siv thaj chaw:

1.Kev lag luam hluav taws xob: Barium feem ntau yog siv los tsim cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob semiconductor, electrolytic capacitors thiab high-frequency cables.

2.Kev lag luam iav: Barium yog siv los ua ib qho ntxiv hauv iav ntau lawm los txhim kho hardness, khawb tsis kam thiab kub tsis kam ntawm iav.

3.Kev lag luam metallurgical:Bariumtuaj yeem siv los rho tawm cov ntsiab lus tseem ceeb ntawm lwm cov hlau ore, xws li tooj liab, txhuas thiab zinc.

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

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