Helu CAS 7783-54-2 Mea Hoʻolako Nitrogen Trifluoride. Nā ʻano o ka Nitrogen Trifluoride
2024-08-01
ʻO ka Nitrogen trifluoride (NF₃) he kinoea waihoʻoluʻu ʻole a ʻala ʻole ma ka lumi wela a me ke kaomi.Loaʻa iā ia ka helu CAS 7783-54-2 a hoʻohana ʻia i nā noi ʻoihana like ʻole, ka mea nui ma ka ʻoihana semiconductor no ka etching plasma a me nā kaʻina hoʻomaʻemaʻe ma muli o kāna hana kemika me nā mea pili i ke silicon.
Nā hiʻohiʻona o ka Nitrogen Trifluoride:
Nā waiwai kemika:
ʻO ka NF₃ kahi mea hoʻokahe ikaika.
Hoʻopili ʻo ia me ka mahu wai e hana i ka waika hydrofluoric (HF), he mea ʻino loa a ʻona.
Hiki ke hoʻoheheʻe i ka wā e ʻike ʻia ai i nā wela kiʻekiʻe a i ʻole ke kukui UV, e hana ana i nā ʻawaʻawa a me nā mea ʻino me ka nitrogen dioxide (NO₂).
Nā waiwai kino:
Puni paila: -129.2°C (-196.6°F)
Ka helu hehee: -207°C (-340.6°F)
Māmā: 3.04 g/L (ma 25°C a me 1 atm)
Nā pilikia palekana:
ʻAʻole hiki ke puhi ʻia ka NF₃ akā hiki ke kākoʻo i ka puhi ʻana.
He pōʻino paha ke hoʻohu ʻia a inā pili ia me ka ʻili a i ʻole nā maka ma muli o kona ʻano hoʻololi a me nā huahana o kona palaho.
Manaʻo ʻia ʻo ia he asphyxiant ma nā kiʻekiʻe kiʻekiʻe no ka mea hiki iā ia ke hoʻololi i ka oxygen i ka lewa.
Ka hopena o ke kaiapuni:
ʻO NF₃ he kinoea hoʻomehana honua ikaika me ka hiki ke hoʻomehana honua ma luna o 17,000 mau manawa ʻoi aʻe ma mua o CO₂ ma kahi manawa 100 makahiki.
