Silaneyog ib qho sib xyaw ntawm silicon thiab hydrogen, thiab yog ib lo lus dav dav rau ib qho ntawm cov sib xyaw. Silane feem ntau suav nrog monosilane (SiH4), disilane (Si2H6) thiab qee cov silicon hydrogen sib xyaw siab dua, nrog rau cov mis dav dav SinH2n + 2. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, peb feem ntau xa mus rau monosilane (tshuaj lom neeg SiH4) ua "silane".

Qib hluav taws xobroj silaneyog feem ntau tau los ntawm ntau yam kev sib xyaw ua ke thiab kev ntxuav ntawm silicon hmoov, hydrogen, silicon tetrachloride, catalyst, thiab lwm yam. Silane nrog qhov huv ntawm 3N txog 4N hu ua industrial-grade silane, thiab silane nrog qhov huv ntawm ntau dua 6N hu ua electronic-grade silane gas.

Ua ib qho chaw roj rau kev nqa cov khoom silicon,roj silanetau dhau los ua ib qho roj tshwj xeeb tseem ceeb uas tsis tuaj yeem hloov los ntawm ntau lwm cov chaw silicon vim nws qhov kev ntshiab siab thiab muaj peev xwm ua tiav kev tswj hwm zoo. Monosilane tsim cov crystalline silicon los ntawm kev ua pyrolysis, uas tam sim no yog ib qho ntawm cov txheej txheem rau kev tsim cov monocrystalline silicon thiab polycrystalline silicon loj hauv ntiaj teb.

Cov yam ntxwv ntawm Silane

Silane (SiH4)yog ib qho roj tsis muaj xim uas cuam tshuam nrog huab cua thiab ua rau tuag tes tuag taw. Nws lub ntsiab lus yog silicon hydride. Cov mis tshuaj ntawm silane yog SiH4, thiab nws cov ntsiab lus yog siab txog li 99.99%. Ntawm chav tsev kub thiab siab, silane yog ib qho roj lom uas muaj ntxhiab tsw phem. Lub ntsiab lus yaj ntawm silane yog -185 ℃ thiab lub ntsiab lus kub yog -112 ℃. Ntawm chav tsev kub, silane ruaj khov, tab sis thaum cua sov txog 400 ℃, nws yuav lwj tag nrho mus rau hauv gaseous silicon thiab hydrogen. Silane yog flammable thiab tawg, thiab nws yuav hlawv tawg hauv huab cua lossis halogen roj.

Cov teb thov

Silane muaj ntau yam kev siv. Ntxiv rau qhov ua tau zoo tshaj plaws los txuas cov silicon molecules rau ntawm qhov chaw ntawm lub cell thaum lub sijhawm tsim cov hnub ci cell, nws kuj tseem siv dav hauv cov chaw tsim khoom xws li semiconductors, cov zaub vaj huam sib luag tiaj tus, thiab cov iav coated.

Silaneyog qhov chaw silicon rau cov txheej txheem tso pa tshuaj lom neeg xws li cov khoom siv lead ua ib leeg silicon, polycrystalline silicon epitaxial wafers, silicon dioxide, silicon nitride, thiab phosphosilicate iav hauv kev lag luam semiconductor, thiab siv dav hauv kev tsim khoom thiab kev txhim kho ntawm cov hlwb hnub ci, silicon copier drums, photoelectric sensors, optical fibers, thiab iav tshwj xeeb.

Nyob rau hauv xyoo tas los no, cov kev siv tshuab silanes tseem tab tom tshwm sim, suav nrog kev tsim cov khoom siv ceramics, cov ntaub ntawv sib xyaw, cov ntaub ntawv ua haujlwm, cov ntaub ntawv biomaterials, cov ntaub ntawv muaj zog, thiab lwm yam, ua lub hauv paus ntawm ntau cov thev naus laus zis tshiab, cov ntaub ntawv tshiab, thiab cov khoom siv tshiab.
