Kodi tungsten hexafluoride amagwiritsidwa ntchito bwanji?
Kodi tungsten hexafluoride amagwiritsidwa ntchito bwanji?
Tungsten hexafluoridendi gasi wopanda mtundu, wapoizoni komanso wowononga kwambiri ndipo kachulukidwe wake ndi pafupifupi 13 g/L, womwe ndi pafupifupi kuwirikiza ka 11 kuchulukira kwa mpweya ndi umodzi mwa mpweya wokhuthala kwambiri. M'makampani a semiconductor, tungsten hexafluoride imagwiritsidwa ntchito makamaka mu ndondomeko ya chemical vapor deposition (CVD) kuyika tungsten zitsulo. Kanema wa tungsten woyikidwa angagwiritsidwe ntchito ngati chingwe cholumikizira kudzera m'mabowo ndi mabowo olumikizana, ndipo ali ndi mawonekedwe otsika kukana komanso malo osungunuka kwambiri. Tungsten hexafluoride imagwiritsidwanso ntchito pakupanga mankhwala, etching ya plasma ndi njira zina.
Kodi gasi wandiweyani kwambiri wopanda poizoni ndi uti?
Gasi wokhuthala kwambiri wopanda poizoni ndi argon (Ar) wokhala ndi kachulukidwe ka 1.7845 g/L. Argon ndi mpweya wochepa, wopanda mtundu komanso wopanda fungo, ndipo sungagwirizane ndi zinthu zina mosavuta. Mpweya wa Argon umagwiritsidwa ntchito makamaka poteteza mpweya, kuwotcherera zitsulo, kudula zitsulo, laser ndi zina.
Kodi tungsten ndi yamphamvu kuposa titaniyamu?
Tungsten ndi titaniyamu ndi zinthu zachitsulo zomwe zimakhala ndi malo osungunuka kwambiri komanso mphamvu. Malo osungunuka a tungsten ndi 3422 ° C ndipo mphamvu ndi 500 MPa, pamene titaniyamu yosungunuka ndi 1668 ° C ndipo mphamvu ndi 434 MPa. Choncho, tungsten ndi wamphamvu kuposa titaniyamu.
Kodi tungsten hexafluoride ndi poizoni bwanji?
Tungsten hexafluoridendi mpweya wapoizoni kwambiri umene ukhoza kuwononga kwambiri thupi la munthu ukaukoka. LD50 ya tungsten hexafluoride ndi 5.6 mg/kg, ndiko kuti, kupuma kwa 5.6 mg wa tungsten hexafluoride pa kilogalamu ya kulemera kwa thupi kudzachititsa kuti 50% amafa. Tungsten hexafluoride imatha kukwiyitsa thirakiti la kupuma, kuchititsa zizindikiro monga chifuwa, chifuwa, ndi dyspnea. Zovuta kwambiri zimatha kuyambitsa edema ya m'mapapo, kulephera kupuma komanso imfa.
Kodi tungsten idzakhala dzimbiri?
Tungsten sichita dzimbiri. Tungsten ndi chitsulo chosagwira ntchito chomwe sichimakhudzidwa mosavuta ndi mpweya mumlengalenga. Choncho, tungsten sizichita dzimbiri pa kutentha kwabwino.
Kodi asidi angawononge tungsten?
Ma acid amatha kuwononga tungsten, koma pang'onopang'ono. Ma asidi amphamvu monga sulfuric acid ndi hydrochloric acid amatha kuwononga tungsten, koma zimatenga nthawi yayitali. Ma acid ofooka monga kusungunula sulfuric acid ndi kusungunula hydrochloric acid amakhala ndi dzimbiri lofooka pa tungsten.
