BARIUM chloride
Barium chloride, nrog rau cov tshuaj formula BaCl2, nthuav tawm cov khoom sib txawv ntawm lub cev. Nws feem ntau tshwm raws li cov xim dawb lossis xim tsis muaj xim crystalline, qee zaus hauv daim ntawv hmoov. Tsis muaj ntxhiab tsw, nws yog heev soluble nyob rau hauv dej, tsim ib tug ntshiab tov. Lub compound boasts ib tug kuj siab melting point nyob ib ncig ntawm 963 degree (1765 degree F), thaum nws boiling point yog surpassed los ntawm decomposition. Nrog ib qhov ceev ntawm kwv yees li 3.856 g / cm³, barium chloride crystallizes nyob rau hauv lub orthorhombic siv lead ua system. Nws cov molar loj yog li 208.23 g / mol. Qhov tseem ceeb, nws yog hygroscopic, absorbing noo noo los ntawm huab cua, thiab deliquescent, dissolving nyob rau hauv absorbed dej. Thaum cov khoom barium chloride nthuav tawm cov hluav taws xob tsis zoo, nws cov kev daws teeb meem aqueous ua hluav taws xob zoo vim ionization. Cov kev daws teeb meem zoo li nruab nrab nrog pH ze rau 7. Tsis tas li ntawd, qhov sib xyaw ua ke ruaj khov nyob rau hauv ib txwm muaj qhov tseem ceeb, txawm tias nws yuav decompose ntawm qhov kub siab heev. Barium chloride yog tshuaj lom thiab yuav tsum tau saib xyuas kom tsis txhob muaj tawv nqaij, qhov muag, los yog mucous daim nyias nyias. Nws cov khoom siv lub cev txhais nws cov khoom siv hauv ntau yam kev lag luam, chav kuaj, thiab kev tshawb fawb siv.

Barium chloride pom ntau yam kev siv thoob plaws hauv kev lag luam:
Laboratory Reagent: Nws ua hauj lwm raws li ib qho reagent nyob rau hauv lub chaw kuaj, tshwj xeeb tshaj yog nyob rau hauv analytical chemistry rau nag lossis daus tshwm sim thiab inorganic synthesis.
Pyrotechnics: Nws yog ua hauj lwm nyob rau hauv zus tau tej cov fireworks ntsuab thiab flares vim nws muaj peev xwm muab ib tug kaj ntsuab xim rau nplaim taws.
Kev Lag Luam Textile: Nws ua haujlwm raws li cov khoom lag luam hauv textile dyeing txheej txheem, pab kho dyes rau fabrics.
Roj Drilling: Nyob rau hauv cov roj kev lag luam, nws yog siv rau hauv cov roj kev lag luam kom nce ntom ntom ntom ntom, tswj kom zoo, thiab tiv thaiv cov tshuab raj.
Brine Purification: Nws ua lub luag haujlwm hauv kev ua kom huv ntawm brine hauv kev lag luam chlor-alkali, pab tshem tawm cov impurities xws li calcium thiab magnesium ions.
