CAS No. 7783 - 82 -6 Tungsten hexafluoride Supplide. Iimpawu zeTungsten hexafluoride
I-Tungsten hexafluoride (WF₆) i-chemical compound kunye nenombolo ye-CAS 7783-82-6. Isetyenziswa ngokubanzi kwishishini le-semiconductor kunye nezinye izicelo zobuchwepheshe obuphezulu ngenxa yeempawu zayo ezizodwa. Nazi ezinye iimpawu eziphambili ze-tungsten hexafluoride:
Iinkcazelo Ngeempawu:
Imbonakalo: I-Tungsten hexafluoride yigesi engenambala kwiqondo lokushisa kunye noxinzelelo.
Indawo yokuBilisa: Malunga ne-12.8°C (55°F).
Indawo yokunyibilika: -59.2°C (-74.6°F).
Ubuninzi: 6.23 g/cm³ ku-25°C.
Ukunyibilika: Ayisebenzi kunye nezinyibilikisi ezininzi eziqhelekileyo kodwa inokusabela ngamanzi okanye ukufuma.
Iinkcazelo ngeMichiza:
Ukuzinza: Izinzile phantsi kweemeko eziqhelekileyo kodwa iyabola xa ibekwe kubushushu okanye kumanzi.
Ukusebenza kwakhona: Isebenza kakhulu ngamanzi kunye nezixhobo ezininzi eziphilayo, ikhupha i-hydrogen fluoride eyityhefu kunye ne-corrosive (HF).
Iingozi zempilo:
Ubutyhefu: I-Tungsten hexafluoride inetyhefu kakhulu ngokuphefumla kwaye inokubangela iingxaki ezinzulu zokuphefumla, kubandakanya nomonakalo wemiphunga.
Corrosivity: Iyadleka eluswini nasemehlweni, kwaye ukutyhileka kunokukhokelela ekutshiseni.
Usebenzisa:
Ishishini leSemiconductor: Isetyenziswa kwiinkqubo zokubeka umphunga wekhemikhali (CVD) ukubekwa kweefilimu ze-tungsten kwi-microelectronics.
I-Metallurgy: Isetyenziselwa ukuveliswa kwee-alloys ezisekelwe kwi-tungsten kunye neekhompawundi.
Uphando: Isetyenziswa kwiinkalo ezahlukeneyo zophando ngenxa yeempawu zayo ezizodwa.
Xa uphethe i-tungsten hexafluoride, soloko usebenzisa izixhobo ezifanelekileyo zokuzikhusela (PPE), sebenza kwindawo enomoya opholileyo okanye ifume hood, kwaye ulandele imigaqo engqongqo yokhuseleko lokuthintela ukuphefumla kunye nokunxibelelana kwesikhumba. Qinisekisa ukuba unokufikelela kwiinkqubo zongxamiseko kunye nezibonelelo zoncedo lokuqala.
