I-CAS No. 7783 - 82 -6 Umhlinzeki we-Tungsten hexafluoride. Izici ze-Tungsten hexafluoride

I-Tungsten hexafluoride (WF₆) iyinhlanganisela yamakhemikhali enenombolo ye-CAS 7783-82-6. Isetshenziswa kabanzi embonini ye-semiconductor nezinye izinhlelo zokusebenza zobuchwepheshe obuphezulu ngenxa yezakhiwo zayo ezihlukile. Nazi ezinye izici ezibalulekile ze-tungsten hexafluoride:

Izakhiwo Zomzimba:
Ukubukeka: I-Tungsten hexafluoride iyigesi engenambala ekamelweni lokushisa nokucindezela.
Indawo yokubilisa: Cishe u-12.8°C (55°F).
Indawo Encibilika: -59.2°C (-74.6°F).
Ukuminyana: 6.23 g/cm³ ku-25°C.
I-Solubility: Ayisebenzi ngezincibilikisi eziningi ezivamile kodwa ingase isabelane namanzi noma umswakama.
Izakhiwo Zekhemikhali:
Ukuzinza: Izinzile ngaphansi kwezimo ezijwayelekile kodwa iyabola lapho ibhekene nokushisa noma umswakama.
Ukusebenza kabusha: Isebenza kakhulu ngamanzi kanye nezinto eziningi eziphilayo, ikhipha i-hydrogen fluoride (HF) enobuthi ne-corrosive.
Izingozi Zezempilo:
Ubuthi: I-Tungsten hexafluoride inobuthi obukhulu ngokuhogela futhi ingabangela izinkinga ezinzima zokuphefumula, okuhlanganisa nokulimala kwamaphaphu.
Ukubola: Kugqwala esikhumbeni nasemahlweni, futhi ukuchayeka kungaholela ekushiseni.
Isebenzisa:
Imboni ye-Semiconductor: Isetshenziswa ezinqubweni ze-chemical vapor deposition (CVD) ukuze kufakwe amafilimu e-tungsten kuma-microelectronics.
I-Metallurgy: Isetshenziswa ekukhiqizeni ama-alloys asekelwe ku-tungsten kanye nezinhlanganisela.
Ucwaningo: Isetshenziswa emikhakheni eyahlukene yocwaningo ngenxa yezakhiwo zayo ezihlukile.
Lapho uphatha i-tungsten hexafluoride, sebenzisa njalo okokuvikela komuntu siqu (i-PPE), sebenzisa endaweni enomoya omuhle noma i-fume hood, futhi ulandele izimiso eziqinile zokuphepha ukuze uvimbele ukuhogela nokuthinta isikhumba. Qinisekisa ukuthi uyakwazi ukufinyelela ezinqubweni eziphuthumayo kanye nezinsiza zosizo lokuqala.
