CAS No. 7783 - 82 -6 Tungsten hexafluoride Supplier. Cov yam ntxwv ntawm Tungsten hexafluoride

Tungsten hexafluoride (WF₆) yog ib qho tshuaj sib xyaw nrog CAS tus lej 7783-82-6. Nws yog dav siv hauv kev lag luam semiconductor thiab lwm yam kev siv high-tech vim nws cov khoom tshwj xeeb. Nov yog qee cov yam ntxwv tseem ceeb ntawm tungsten hexafluoride:

Lub cev muaj zog:
Cov tsos mob: Tungsten hexafluoride yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab.
Boiling Point: Kwv yees li 12.8 ° C (55 ° F).
Melting Point: -59.2 ° C (-74.6 ° F).
Qhov ceev: 6.23 g / cm³ ntawm 25 ° C.
Solubility: Nws yog non-reactive nrog ntau cov kuab tshuaj tab sis tej zaum yuav hnov ​​mob nrog dej los yog noo noo.
Chemical Properties:
Stability: ruaj khov nyob rau hauv ib txwm muaj tab sis decomposes thaum raug tshav kub los yog ya raws.
Reactivity: Nws yog reactive heev nrog dej thiab feem ntau cov ntaub ntawv organic, tso tshuaj lom thiab corrosive hydrogen fluoride (HF).
Kev Nyab Xeeb Kev Nyab Xeeb:
Toxicity: Tungsten hexafluoride yog tshuaj lom heev los ntawm kev nqus pa thiab tuaj yeem ua rau muaj teeb meem ua pa hnyav, nrog rau lub ntsws puas.
Corrosivity: Nws yog corrosive rau ntawm daim tawv nqaij thiab ob lub qhov muag, thiab kis tau tuaj yeem ua rau kub hnyiab.
Kev siv:
Kev Lag Luam Semiconductor: Nws yog siv rau hauv cov txheej txheem tshuaj vapor deposition (CVD) rau kev tso tawm ntawm tungsten films hauv microelectronics.
Metallurgy: Siv nyob rau hauv kev tsim cov tungsten-based alloys thiab compounds.
Kev Tshawb Fawb: Siv ntau yam kev tshawb fawb vim nws cov khoom tshwj xeeb.
Thaum tuav cov tungsten hexafluoride, ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo lossis cov fume hood, thiab ua raws li cov txheej txheem kev nyab xeeb nruj kom tsis txhob nqus tau thiab tiv thaiv daim tawv nqaij. Xyuas kom koj muaj kev nkag mus rau cov txheej txheem xwm txheej ceev thiab cov chaw pab thawj zaug.
