I-CAS No. 7803-51-2 Umphakeli wePhosphine. Izici zePhosphine
I-Phosphine (PH₃) igesi engenambala, evutha umlilo enephunga elinobuthi obuyingozi kakhulu kubantu. Ifana ngamakhemikhali ne-ammonia (NH₃), kodwa ayiyisisekelo futhi iyasebenza kakhulu. I-Phosphine isetshenziswa emisebenzini ehlukahlukene yezimboni, okuhlanganisa imboni ye-semiconductor ye-doping silicon ne-gallium arsenide, ekukhiqizeni i-phosphides yensimbi, nanjengemfucuza kwezolimo.
Nazi ezinye izici ezibalulekile ze-phosphine:
Izakhiwo Zekhemikhali:
Ifomula yemolekyuli: PH₃
Isisindo sengqamuzana: 33.99776 g/mol
Inombolo ye-CAS: 7803-51-2
Indawo yokubilisa: -87.8 °C
Indawo yokuncibilika: -133.3 °C
Ukuminyana: 1.634 g/L ku-STP (izinga lokushisa elijwayelekile nokucindezela)
Izakhiwo Zomzimba:
I-Phosphine igesi engenambala ekamelweni lokushisa kanye nokucindezela.
Iyakwazi ukuvutha futhi ingavutha ngokuzenzekelayo lapho ibekwe emoyeni ngenxa yokusebenza kwayo kabusha okuphezulu.
Ubuthi:
I-Phosphine inobuthi obukhulu ngokuhogela, idala umonakalo omkhulu wamaphaphu futhi ingaholela ekufeni.
Ibuye ibe nobuthi uma igwinywa noma imuncwe esikhumbeni.
Isebenzisa:
Ekwenziweni kwe-semiconductor yezinqubo ze-doping.
Njengofumigant endaweni yokugcina okusanhlamvu ukulawula izinambuzane.
Ekuhlanganisweni kwe-organophosphorus compounds.
Ukuphatha kanye Nesitoreji:
I-Phosphine kumele iphathwe ngokucophelela ngenxa yobuthi bayo nokuvutha.
Kufanele igcinwe endaweni epholile, eyomile kude nanoma yimuphi umthombo wokuthungela.
Kudingeka izinyathelo ezikhethekile zokuvikela ukuvimbela ukuvuza noma ukuchitheka.
I-Shanghai Wechem Chemical Co., Ltd. inemishini ethuthukisiwe nobuchwepheshe bokuhlaziya elabhorethri yayo, iqinisekisa ukuthi singakwazi ukulawula nokuhlola ikhwalithi yomkhiqizo okunembile. Samukela isistimu yokuphatha ikhwalithi eqinile, ukuqapha nokuphatha zonke izinyathelo ukusuka ekuthengeni impahla eluhlaza ukuya ekukhiqizweni ukuze siqinisekise ukuthi imikhiqizo esiyihlinzekayo ihlangabezana namazinga aphezulu kakhulu. Uma udinga lo mkhiqizo, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi!
