Kodi silane amapangidwa bwanji?
(1) Magnesium silicide njira: chitani ufa wosakanikirana wa silicon ndi magnesium mu haidrojeni pafupifupi 500 ° C, ndikuchitani ndi magnesium silicide yopangidwa ndi ammonium chloride mumadzi otsika ammonia ammonia kuti mupeze silane. Kuyeretsedwa kwa izo mu distillation chipangizo utakhazikika ndi madzi asafe ndi zokolola koyera silane.
(2) Heterogeneous reaction method: tani silicon ufa, silicon tetrachloride ndi haidrojeni mu ng'anjo fluidized bedi kutentha pamwamba 500 ° C kupeza trichlorosilane. Trichlorosilane imasiyanitsidwa ndi distillation. Dichlorosilane imapezeka mwamachitidwe osiyanasiyana pamaso pa chothandizira. The analandira dichlorosilane ndi osakaniza pakachitsulo tetrachloride ndi trichlorosilane, kotero koyera dichlorosilane akhoza analandira pambuyo distillation. Trichlorosilane ndi monosilane amatengedwa kuchokera ku dichlorosilane pogwiritsa ntchito chothandizira chosiyanasiyana. The analandira monosilane amayeretsedwa ndi otsika kutentha mkulu-anzanu distillation chipangizo.
(3) Tengani aloyi ya silicon-magnesium ndi hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy imakumana ndi ammonium bromide mu ammonia yamadzi.
(5) Pogwiritsa ntchito lithiamu aluminium hydride, lithiamu borohydride, etc. monga kuchepetsa, kuchepetsa tetrachlorosilane kapena trichlorosilane mu ether.
2. Kodi poyambira silane ndi chiyani?
The zopangira kwa yokonzasilanemakamaka silicon ufa ndi haidrojeni. Zofunikira zaukhondo wa silicon ufa ndizokwera kwambiri, nthawi zambiri zimafika kuposa 99.999%. Hydrojeni imayengedwanso kuti iwonetsetse kuyera kwakukulu kwa silane yokonzedwa.
3. Kodi ntchito ya silane ndi chiyani?
Monga gwero la gasi lomwe limapereka zida za silicon, silane ingagwiritsidwe ntchito kupanga silicon yoyera kwambiri ya polycrystalline, silicon imodzi ya crystal, silicon ya microcrystalline, silikoni ya amorphous, silicon nitride, silicon oxide, silicon silicon, silicon wosiyanasiyana, ndi masilidi osiyanasiyana achitsulo. Chifukwa cha chiyero chake chachikulu komanso kuwongolera bwino, yakhala mpweya wofunikira kwambiri womwe sungathe kusinthidwa ndi magwero ena ambiri a silicon. Silane imagwiritsidwa ntchito kwambiri m'mafakitale a microelectronics ndi optoelectronics, ndipo imagwiritsidwa ntchito popanga ma cell a solar, mawonedwe apansi, magalasi ndi zokutira zachitsulo, ndipo ndi chinthu chokhacho chapakatikati padziko lonse lapansi popanga silicon yoyera kwambiri ya granular. Mapulogalamu apamwamba kwambiri a silane akadali akutuluka, kuphatikizapo kugwiritsidwa ntchito popanga zoumba zapamwamba, zipangizo zophatikizika, zipangizo zogwirira ntchito, biomatadium, zipangizo zamagetsi, ndi zina zotero, ndikukhala maziko a umisiri watsopano, zipangizo zatsopano, ndi zina zotero. zida zatsopano.
4. Kodi ma silanes amateteza chilengedwe?
Inde, mankhwala a silane alibe ma ion zitsulo zolemera ndi zowononga zina, ndipo amagwirizana ndi ROHS ndi SGS miyezo yoteteza chilengedwe.
5. Kugwiritsa ntchito silane
Mapangidwe a mafupa a chlorosilanes ndi alkyl chlorosilanes, kukula kwa epitaxial kwa silicon, zopangira za polysilicon, silicon oxide, silicon nitride, ndi zina zotero, maselo a dzuwa, ulusi wa kuwala, kupanga magalasi achikuda, kuyika kwa nthunzi ya mankhwala.
