Silaneyog ib qho kev sib xyaw ntawm silicon thiab hydrogen, thiab yog ib lub ntsiab lus dav dav rau cov khoom sib txuas. Silane feem ntau suav nrog monosilane (SiH4), disilane (Si2H6) thiab qee cov qib siab ntawm silicon hydrogen compounds, nrog rau cov qauv dav dav SinH2n + 2. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, peb feem ntau xa mus rau monosilane (cov tshuaj formula SiH4) ua "silane".
Electronic-qibsiv gasFeem ntau yog tau los ntawm ntau yam tshuaj distillation thiab purification ntawm silicon hmoov, hydrogen, silicon tetrachloride, catalyst, thiab lwm yam Silane nrog ib tug purity ntawm 3N txog 4N yog hu ua industrial-qib silane, thiab silane nrog ib tug purity ntawm ntau tshaj 6N yog hu ua electronic- qib silane gas.
Raws li cov pa roj rau nqa cov khoom siv silicon,siv gastau dhau los ua cov pa roj tshwj xeeb tseem ceeb uas tsis tuaj yeem hloov tau los ntawm ntau lwm qhov chaw silicon vim nws cov purity siab thiab muaj peev xwm ua tau zoo tswj. Monosilane tsim cov crystalline silicon los ntawm cov tshuaj tiv thaiv pyrolysis, uas tam sim no yog ib txoj hauv kev rau kev loj hlob ntawm granular monocrystalline silicon thiab polycrystalline silicon hauv ntiaj teb.
Cov yam ntxwv ntawm Silane
Silane (SiH4)yog cov roj uas tsis muaj xim uas ua rau huab cua thiab ua rau tuag taus. Nws lub ntsiab lus yog silicon hydride. Cov tshuaj formula ntawm silane yog SiH4, thiab nws cov ntsiab lus siab li 99.99%. Nyob rau hauv chav tsev kub thiab siab, silane yog ib tug pa phem pa phem. Lub melting point ntawm silane yog -185 ℃ thiab boiling point -112 ℃. Nyob rau hauv chav tsev kub, silane ruaj khov, tab sis thaum rhuab mus rau 400 ℃, nws yuav decompose tag rau hauv gaseous silicon thiab hydrogen. Silane yog flammable thiab tawg, thiab nws yuav hlawv explosively nyob rau hauv huab cua los yog halogen roj.
Daim ntawv thov teb
Silane muaj ntau yam kev siv. Ntxiv rau qhov ua tau zoo tshaj plaws los txuas cov silicon molecules rau saum npoo ntawm tes thaum lub sij hawm tsim cov hnub ci, nws kuj tau siv dav hauv kev tsim cov nroj tsuag xws li semiconductors, vaj huam sib luag tiaj tus, thiab cov iav coated.
Silaneyog silicon qhov chaw rau tshuaj vapor deposition txheej txheem xws li ib tug siv lead ua silicon, polycrystalline silicon epitaxial wafers, silicon dioxide, silicon nitride, thiab phosphosilicate iav nyob rau hauv lub semiconductor kev lag luam, thiab yog dav siv nyob rau hauv kev tsim thiab kev loj hlob ntawm lub hnub ci hlwb, silicon copier nruas. , photoelectric sensors, optical fibers, thiab iav tshwj xeeb.
Nyob rau hauv xyoo tas los no, kev siv thev naus laus zis ntawm silanes tseem tab tom tshwm sim, suav nrog kev tsim cov ceramics siab heev, cov ntaub ntawv sib xyaw, cov khoom siv, biomaterials, cov khoom siv hluav taws xob siab, thiab lwm yam, ua lub hauv paus ntawm ntau cov thev naus laus zis tshiab, cov ntaub ntawv tshiab, thiab cov khoom tshiab. khoom siv.
