Yini i-silane?

Silaneiyinhlanganisela ye-silicon ne-hydrogen, futhi iyitemu evamile yochungechunge lwezinhlanganisela. I-Silane ikakhulukazi ihlanganisa i-monosilane (SiH4), i-disilane (Si2H6) nezinye izinhlanganisela ze-silicon hydrogen ezisezingeni eliphezulu, ezinefomula evamile i-SinH2n+2. Kodwa-ke, ekukhiqizeni kwangempela, ngokuvamile sibhekisela ku-monosilane (ifomula yamakhemikhali i-SiH4) ngokuthi "silane".

I-Electronic-gradeigesi ye-silaneikakhulukazi etholwe ezihlukahlukene ukusabela ziphuzo zazihluzwa kanye ukuhlanzwa Silicon powder, hydrogen, Silicon tetrachloride, catalyst, njll Silane nobumsulwa 3N kuya 4N ibizwa ngokuthi i-industrial-grade silane, futhi silane ngobumsulwa kuka 6N ibizwa ngokuthi electronic- igesi ye-silane yezinga.

Njengomthombo wegesi wokuthwala izingxenye ze-silicon,igesi ye-silaneiye yaba igesi ekhethekile ebalulekile engakwazi ukushintshwa eminye imithombo eminingi ye-silicon ngenxa yokuhlanzeka kwayo okuphezulu kanye nekhono lokufeza ukulawula okuhle. I-Monosilane ikhiqiza i-crystalline silicon ngokusabela kwe-pyrolysis, okwamanje okungenye yezindlela zokukhiqiza okukhulu kwe-silicon ye-granular monocrystalline kanye ne-polycrystalline silicon emhlabeni.

Silane izici

I-Silane (SiH4)igesi engenambala esabela emoyeni futhi ibangele ukuminza. Igama layo elifanayo yi-silicon hydride. I-chemical formula ye-silane yi-SiH4, futhi okuqukethwe kwayo kuphezulu njengo-99.99%. Ezingeni lokushisa elivamile nokucindezela, i-silane iyigesi enobuthi enuka kabi. Iphuzu elincibilikayo le-silane lingu-185℃ kanti indawo yokubilisa ingu -112℃. Emazingeni okushisa asekamelweni, i-silane izinzile, kodwa uma ishisiswe ibe ngu-400 ℃, izobola ibe yi-silicon eyigesi ne-hydrogen. I-Silane iyavutha futhi iyaqhuma, futhi izoshisa kakhulu emoyeni noma kugesi we-halogen.

Izinkambu zohlelo lokusebenza

I-Silane inezinhlobonhlobo zokusetshenziswa. Ngaphezu kokuba indlela ephumelela kakhulu yokunamathisela ama-molecule e-silicon ebusweni beseli ngesikhathi sokukhiqizwa kwamaseli elanga, ibuye isetshenziswe kabanzi ekukhiqizeni izitshalo ezifana nama-semiconductors, imibukiso yamaphaneli ayisicaba, nezingilazi ezimboziwe.

Silaneiwumthombo we-silicon wezinqubo zokubeka umhwamuko wamakhemikhali njenge-single crystal silicon, i-polycrystalline silicon epitaxial wafers, i-silicon dioxide, i-silicon nitride, nengilazi ye-phosphosilicate embonini ye-semiconductor, futhi isetshenziswa kabanzi ekukhiqizeni nasekuthuthukisweni kwamaseli elanga, izigubhu ze-silicon copier. , izinzwa ze-photoelectric, ama-optical fibers, nengilazi ekhethekile.

Eminyakeni yamuva nje, ukusetshenziswa kwe-high-tech yama-silanes kusavela, okuhlanganisa ukwakhiwa kwezitsha zobumba ezithuthukisiwe, izinto eziyinhlanganisela, izinto zokusebenza, ama-biomaterials, izinto ezisebenza ngamandla amakhulu, njll., okuba yisisekelo sobuchwepheshe obuningi obusha, izinto ezintsha, nezinto ezintsha. amadivaysi.
