CAS No. 7803-51-2 Phosphine Supplier. Cov yam ntxwv ntawm Phosphine
Phosphine (PH₃) yog cov roj uas tsis muaj xim, flammable nrog cov ntxhiab tsw uas muaj tshuaj lom rau tib neeg. Nws yog tshuaj lom neeg zoo ib yam li ammonia (NH₃), tab sis nws tsis tshua yooj yim thiab ntau reactive. Phosphine yog siv nyob rau hauv ntau daim ntawv thov kev lag luam, nrog rau kev lag luam semiconductor rau doping silicon thiab gallium arsenide, hauv kev tsim cov hlau phosphides, thiab ua fumigant hauv kev ua liaj ua teb.
Nov yog qee cov yam ntxwv tseem ceeb ntawm phosphine:
Chemical Properties:
Cov mis mos molecular: PH ₃
Molecular Luj: 33.99776 g / mol
CAS Nr .: 7803-51-2
Kub taw tes: -87.8 ° C
Melting point: -133.3 ° C
Ceev: 1.634 g / L ntawm STP (tus qauv kub thiab siab)
Lub cev muaj zog:
Phosphine yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab.
Nws yog flammable thiab tuaj yeem ignite spontaneously thaum raug huab cua vim nws siab reactivity.
Toxicity:
Phosphine yog tshuaj lom heev los ntawm kev nqus pa, ua rau mob ntsws loj thiab tuaj yeem ua rau tuag taus.
Nws kuj yog tshuaj lom yog tias nqos los yog nqus los ntawm daim tawv nqaij.
Kev siv:
Nyob rau hauv semiconductor manufacturing rau doping txheej txheem.
Raws li ib tug fumigant nyob rau hauv grain cia los tswj kab tsuag.
Nyob rau hauv lub synthesis ntawm organophosphorus tebchaw.
Kev tuav thiab khaws cia:
Phosphine yuav tsum tau ua tib zoo saib xyuas vim nws cov toxicity thiab flammability.
Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav kom deb ntawm txhua qhov chaw ntawm qhov hluav taws kub.
Kev ceev faj tshwj xeeb yog tsim nyog los tiv thaiv kev xau los yog nchuav.
