CAS No. 7783-54-2 Nitrogen Trifluoride Supplier. Cov yam ntxwv ntawm Nitrogen Trifluoride
2024-08-01 IB
Nitrogen trifluoride (NF₃) yog cov roj tsis muaj xim, tsis muaj ntxhiab tsw ntawm chav tsev kub thiab siab.Nws muaj tus lej CAS 7783-54-2 thiab yog siv rau hauv ntau daim ntawv thov kev lag luam, feem ntau hauv kev lag luam semiconductor rau plasma etching thiab ntxuav cov txheej txheem vim nws cov tshuaj reactivity nrog cov ntaub ntawv silicon.
Cov yam ntxwv ntawm Nitrogen Trifluoride:
Chemical Properties:
NF₃ yog ib qho muaj zog oxidizing tus neeg sawv cev.
Nws reacts nrog dej vapor los tsim hydrofluoric acid (HF), uas yog heev corrosive thiab lom.
Nws tuaj yeem decompose thaum raug kub lossis UV teeb, tsim cov pa phem thiab corrosive nrog rau nitrogen dioxide (NO₂).
Lub cev muaj zog:
Kub taw tes: -129.2 ° C (-196.6 ° F)
Melting point: -207 ° C (-340.6 ° F)
Ceev: 3.04 g / L (ntawm 25 ° C thiab 1 atm)
Kev txhawj xeeb txog kev nyab xeeb:
NF₃ yog non-flammable tab sis tuaj yeem txhawb kev sib txuas.
Nws muaj peev xwm ua rau muaj kev phom sij yog tias nqus tau los yog nws nkag mus rau hauv daim tawv nqaij lossis qhov muag vim nws qhov tshwm sim thiab cov khoom ntawm nws cov decomposition.
Nws raug suav hais tias yog asphyxiant ntawm qhov siab siab vim tias nws tuaj yeem tso pa oxygen hauv huab cua.
Environmental Impact:
NF₃ yog lub tsev cog khoom muaj zog nrog lub ntiaj teb ua kom sov muaj peev xwm tshaj 17,000 npaug ntau dua CO₂ tshaj li 100 xyoo.
