Helu CAS 7783-61-1 Mea Hoʻolako Silicon Tetrafluoride. Nā ʻano o ka Silicon Tetrafluoride

ʻO ka Silicon tetrafluoride (SiF4) he mea hoʻohui kemika i loaʻa ka hoʻohana ʻana i nā ʻoihana like ʻole, ʻoi loa i ka hana semiconductor a me nā kemika inorganic. Eia kekahi mau hiʻohiʻona nui o ka silicon tetrafluoride:

Nā waiwai kemika:
Kumu: SiF4
Kaumaha Molekala: Ma kahi o 88.10 g/mol
Helu CAS: 7783-61-1
Lahi paila: -87 °C
Lae hehee: -90.2 °C
Nā waiwai kino:
He kinoea kala ʻole ʻo Silicon tetrafluoride ma ka lumi wela a me ke kaomi.
Loaʻa iā ia kahi ʻala ʻala.
He tetrahedral ka mole, e like me ka methane (CH4).
ʻO ka hana hou ʻana:
He pūhui hoʻoheheʻe loa ia, ʻoi loa me ka wai, e hana ana i ka waika hydrofluoric (HF) a me ka silica (SiO2).
ʻO SiF4 kahi mea hana fluorinating ikaika a hiki ke hana me ka nui o nā metala e hana i nā fluoride metala.
Hoʻohana:
ʻOihana Semiconductor: Hoʻohana ʻia i nā kaʻina hana etching plasma e wehe i nā ʻāpana silicon dioxide (SiO2) i nā microelectronics.
Kemika Inorganic: Ma ke ʻano he reagent i ka synthesis o nā pūhui silika ʻē aʻe.
Analytical Chemistry: I ka hoʻoholo 'ana i ka silikona a me nā mea 'ē aʻe i loko o nā laʻana.
Noiʻi: Ma nā haʻawina e pili ana i ke kemika organofluorine a me ke kemika silika.
Ka lawelawe a me ka palekana:
ʻO ka silikoni tetrafluoride he mea ʻawaʻawa a ʻinoʻino, e hōʻeha ana i nā pilikia olakino e pili ana i ka ʻeha hanu a me ka pōʻino i nā maka a me ka ʻili.
Pono e mālama ʻia ma lalo o nā kūlana inert a me nā lako pale pilikino kūpono (PPE), me nā mīkina lima, nā maka aniani, a me kahi respirator.
Pono e waiho ʻia ma kahi maloʻo maloʻo mai nā mea like ʻole.
Inā makemake ʻoe i ka loaʻa ʻana o ka silicon tetrafluoride no nā kumu ʻoihana a noiʻi paha, pono ʻoe e hoʻopili pololei i kēia mau mea hoʻolako a e hōʻoia i ka hoʻokō ʻia ʻana o nā koi palekana a me ke kānāwai ma mua o ka hoʻomaka ʻana me nā kālepa.
