Ta yaya ake kera silanes?
(1) Hanyar siliki na Magnesium: amsa gauraye foda na silicon da magnesium a cikin hydrogen a kusan 500 ° C, kuma amsa da samar da magnesium silicide tare da ammonium chloride a cikin ƙananan zafin jiki na ammonia don samun silane. Tsarkake shi a cikin na'urar distillation sanyaya tare da ruwa nitrogen yana haifar da silane mai tsabta.
(2) Hanyar amsawa iri-iri: amsa siliki foda, silicon tetrachloride da hydrogen a cikin tanderun gado na ruwa mai zafi sama da 500 ° C don samun trichlorosilane. Trichlorosilane yana rabu da distillation. Ana samun Dichlorosilane ta hanyar halayen daban-daban a gaban mai kara kuzari. Dichlorosilane da aka samu shine cakuda da silicon tetrachloride da trichlorosilane, don haka ana iya samun dichlorosilane mai tsafta bayan distillation. Trichlorosilane da monosilane ana samun su daga dichlorosilane ta yin amfani da mai kara kuzari iri-iri. Ana tsarkake monosilane da aka samu ta na'urar distillation mai ƙarancin zafin jiki.
(3) Yi maganin silicon-magnesium gami da hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy yana amsawa tare da ammonium bromide a cikin ammoniya ruwa.
(5) Yin amfani da lithium aluminum hydride, lithium borohydride, da dai sauransu a matsayin rage wakilai, rage tetrachlorosilane ko trichlorosilane a cikin ether.
2. Menene farkon kayan silane?
A albarkatun kasa domin shiri nasilanesu ne yafi silicon foda da hydrogen. Bukatun tsabta na silicon foda suna da inganci, gabaɗaya sun kai fiye da 99.999%. Ana kuma tace sinadarin hydrogen don tabbatar da tsaftar silane da aka shirya.
3. Menene aikin silane?
A matsayin tushen iskar gas wanda ke samar da abubuwan siliki, ana iya amfani da silane don kera siliki mai tsabta mai tsabta, silicon crystal silicon guda ɗaya, silicon microcrystalline, silicon amorphous, silicon nitride, silicon oxide, silicon daban-daban, da silicides na ƙarfe daban-daban. Saboda girman tsarkinsa da kulawa mai kyau, ya zama muhimmin iskar gas na musamman wanda ba za a iya maye gurbinsa da sauran maɓuɓɓugan silicon ba. Ana amfani da Silane sosai a cikin masana'antar microelectronics da masana'antar optoelectronics, kuma ana amfani dashi wajen kera sel na hasken rana, nunin panel na lebur, gilashin da murfin karfe, kuma shine kawai matsakaicin samfuri a cikin duniya don samar da manyan sikeli na granular high-tsarki silicon. Aikace-aikacen fasaha na silane har yanzu suna tasowa, ciki har da yin amfani da kayan aiki na ci gaba na yumbura, kayan haɗin kai, kayan aiki, kayan aiki, biomaterials, kayan aiki masu ƙarfi, da dai sauransu, kuma sun zama tushen yawancin sababbin fasaha, sababbin kayan aiki, da dai sauransu. sababbin na'urori.
4. Shin silanes suna da alaƙa da muhalli?
Ee, wakili na silane ba ya ƙunshi ions ƙarfe mai nauyi da sauran gurɓatattun abubuwa, kuma yana bin ka'idodin kare muhalli na ROHS da SGS.
5. Aikace-aikacen silane
Tsarin kwarangwal na chlorosilanes da alkyl chlorosilanes, haɓakar epitaxial na silicon, albarkatun ƙasa na polysilicon, silicon oxide, silicon nitride, da dai sauransu, ƙwayoyin hasken rana, fiber na gani, masana'antar gilashin launi, jigilar sinadarai.
