CAS No. 7783-61-1 Silicon Tetrafluoride Supplier. Cov yam ntxwv ntawm Silicon Tetrafluoride
Silicon tetrafluoride (SiF4) yog cov tshuaj sib xyaw ua ke uas pom cov ntawv thov hauv ntau qhov kev lag luam, tshwj xeeb hauv kev tsim khoom semiconductor thiab inorganic chemistry. Nov yog qee cov yam ntxwv tseem ceeb ntawm silicon tetrafluoride:
Chemical Properties:
Cov roj formula: SiF4
Molecular Luj: Kwv yees li 88.10 g / mol
CAS Nr .: 7783-61-1
Kub taw tes: -87 ° C
Melting Point: -90.2 ° C
Lub cev muaj zog:
Silicon tetrafluoride yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab.
Nws muaj tus yam ntxwv pungent tsw.
Cov molecule yog tetrahedral hauv cov qauv, zoo ib yam li methane (CH4).
Reactivity:
Nws yog ib qho tshuaj reactive heev, tshwj xeeb tshaj yog nrog dej, tsim hydrofluoric acid (HF) thiab silica (SiO2).
SiF4 yog ib tug muaj zog fluorinating tus neeg sawv cev thiab tuaj yeem hnov mob nrog cov hlau feem ntau los tsim cov fluorides hlau.
Kev siv:
Kev lag luam semiconductor: Siv cov txheej txheem plasma etching kom tshem tawm cov txheej txheem silicon dioxide (SiO2) hauv microelectronics.
Inorganic Chemistry: Raws li ib tug reagent nyob rau hauv lub synthesis ntawm lwm yam silicon tebchaw.
Analytical Chemistry: Hauv kev txiav txim siab ntawm silicon thiab lwm yam hauv cov qauv.
Kev tshawb fawb: Hauv kev tshawb fawb txog organofluorine chemistry thiab silicon chemistry.
Kev tuav thiab kev nyab xeeb:
Silicon tetrafluoride yog cov tshuaj lom thiab corrosive, ua rau muaj kev phom sij loj rau kev noj qab haus huv nrog rau kev ua pa ua pa thiab puas rau lub qhov muag thiab tawv nqaij.
Nws yuav tsum tau ua raws li cov xwm txheej tsis zoo thiab nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog hnab looj tes, tsom iav, thiab lub tshuab ua pa.
Kev khaws cia yuav tsum nyob hauv qhov chaw txias, qhuav kom deb ntawm cov khoom siv tsis sib xws.
Yog tias koj xav tau silicon tetrafluoride rau kev lag luam raug cai lossis kev tshawb fawb, koj yuav tsum hu rau cov neeg muag khoom ncaj qha thiab xyuas kom meej tias tag nrho cov kev nyab xeeb tsim nyog thiab kev cai lij choj tau ua tiav ua ntej pib ua lag luam.
