Silaneyikhompawundi yesilicon kunye nehydrogen, kwaye ligama jikelele kuthotho iikhompawundi. I-Silane ikakhulu ibandakanya i-monosilane (i-SiH4), i-disilane (i-Si2H6) kunye nezinye iindawo eziphezulu ze-silicon hydrogen compounds, kunye ne-formula jikelele i-SinH2n + 2. Nangona kunjalo, kwimveliso yangempela, ngokuqhelekileyo sibhekisela kwi-monosilane (i-chemical formula SiH4) njenge "silane".

Ibakala le-elektronikiigesi yesilaneubukhulu becala efunyenwe distillation ezahlukeneyo reaction kunye nokusulungekiswa lesilicon umgubo, hydrogen, lesilicon tetrachloride, catalyst, njl Silane ngobunyulu 3N ukuya 4N ibizwa ngokuba yi-industrial-grade silane, kunye ne-silane enobunyulu obungaphezulu kwe-6N ibizwa ngokuba yi-electronic-grade silane gas.

Njengomthombo wegesi wokuthwala izinto ze-silicon,igesi yesilaneiye yaba yirhasi ekhethekileyo ebalulekileyo engenakutshintshwa yimithombo emininzi ye-silicon ngenxa yokucoceka kwayo okuphezulu kunye nokukwazi ukufikelela kulawulo oluhle. I-Monosilane ivelisa i-silicon ye-crystalline nge-pyrolysis reaction, okwangoku enye yeendlela zokuvelisa i-silicon ye-granular monocrystalline kunye ne-polycrystalline silicon emhlabeni.

Iimpawu zeSilane

I-Silane (SiH4)yigesi engenambala edibana nomoya kwaye ibangele ukufuthaniselwa. Isithethantonye sayo yisilicon hydride. I-chemical formula ye-silane yi-SiH4, kwaye umxholo wayo uphezulu njenge-99.99%. Kubushushu begumbi nakuxinzelelo, i-silane yigesi enetyhefu enuka kakubi. Indawo yokunyibilika ye-silane yi -185℃ kwaye indawo yokubila yi -112℃. Kwiqondo lobushushu begumbi, i-silane izinzile, kodwa xa ishushu kwi-400 ℃, iya kubola ngokupheleleyo ibe yi-silicon yegesi kunye ne-hydrogen. ISilane iyatsha kwaye iyaqhushumba, kwaye iya kutsha ngokuqhushumba emoyeni okanye kwirhasi yehalogen.

Iinkalo zesicelo

ISilane inoluhlu olubanzi losetyenziso. Ukongeza kweyona ndlela isebenzayo yokuncamathisela iimolekyuli ze-silicon kumphezulu weseli ngexesha lokuveliswa kweeseli zelanga, ikwasetyenziswa ngokubanzi kwizityalo zokuvelisa ezifana ne-semiconductors, imiboniso yephaneli ecaba, kunye neglasi egqunyiweyo.

Silanengumthombo wesilicon kwiinkqubo zokubeka umphunga wekhemikhali ezifana ne-crystal silicon enye, i-polycrystalline silicon epitaxial wafers, i-silicon dioxide, i-silicon nitride, kunye neglasi ye-phosphosilicate kushishino lwe-semiconductor, kwaye isetyenziswa ngokubanzi kwimveliso kunye nophuhliso lweeseli zelanga, i-silicon copier drums, i-photoelectric sensors, i-optical fibers, kunye ne-fibers ekhethekileyo yeglasi.

Kwiminyaka yakutshanje, ukusetyenziswa kobuchwepheshe obuphezulu be-silanes zisavela, kubandakanywa ukuveliswa kweeseramics eziphambili, izinto ezidibeneyo, izinto ezisebenzayo, i-biomaterials, izixhobo eziphezulu zamandla, njl., zibe sisiseko sobugcisa obuninzi obutsha, izinto ezintsha kunye nezixhobo ezintsha.
