Silane (SiH4)

Magawo aukadaulo

Silane ndi mankhwala opangidwa ndi silicon ndi hydrogen. Ndi mawu ofala a mitundu yosiyanasiyana ya mankhwala, kuphatikizapo monosilane (SiH4), disilane (Si2H6) ndi mankhwala ena apamwamba a silicon-hydrogen. Pakati pawo, monosilane ndiye wofala kwambiri, nthawi zina amatchedwa silane mwachidule. Silane ndi mpweya wopanda mtundu wokhala ndi fungo lonyansa la adyo. Amasungunuka m'madzi, pafupifupi osasungunuka mu ethanol, ether, benzene, chloroform, silicon chloroform ndi silicon tetrachloride. Mankhwala a silane amagwira ntchito kwambiri kuposa alkanes ndipo amasungunuka mosavuta. Kuyaka mwadzidzidzi kumatha kuchitika mukakhudzana ndi mpweya. Sichita ndi nayitrogeni pansi pa 25°C, ndipo sichichita ndi mankhwala a hydrocarbon kutentha kwa chipinda. Moto ndi kuphulika kwa silane zimachitika chifukwa cha kuchita ndi mpweya. Silane imakhudzidwa kwambiri ndi mpweya ndi mpweya. Silane yokhala ndi kuchuluka kwina imachitanso mwamphamvu ndi mpweya pa kutentha kwa -180°C. Silane yakhala mpweya wapadera wofunikira kwambiri womwe umagwiritsidwa ntchito mu njira zama microelectronics za semiconductor, ndipo umagwiritsidwa ntchito pokonza mafilimu osiyanasiyana a microelectronic, kuphatikizapo mafilimu a kristalo amodzi, microcrystalline, polycrystalline, silicon oxide, silicon nitride, ndi metal silicides. Kugwiritsa ntchito silane mu microelectronic kukupitilirabe kukula mozama: epitaxy yotsika kutentha, epitaxy yosankha, ndi heteroepitaxial epitaxy. Sikuti kokha pazida za silicon ndi ma circuits ophatikizidwa ndi silicon, komanso pazida za semiconductor (gallium arsenide, silicon carbide, ndi zina). Imagwiranso ntchito pokonza zinthu za superlattice quantum well. Tinganene kuti silane imagwiritsidwa ntchito pafupifupi m'mizere yonse yapamwamba yopanga ma circuits masiku ano. Kugwiritsa ntchito silane ngati filimu ndi zokutira zokhala ndi silicon kwakula kuchokera kumakampani achikhalidwe a microelectronics kupita kumadera osiyanasiyana monga chitsulo, makina, mankhwala ndi optics. Kugwiritsa ntchito kwina komwe kungachitike kwa silane ndikupanga zida zamainjini za ceramic zogwira ntchito kwambiri, makamaka kugwiritsa ntchito silane popanga silicide (Si3N4, SiC, ndi zina). Ukadaulo wa micropowder wakopa chidwi chachikulu.

Ntchito:

①Zamagetsi:

Silane imagwiritsidwa ntchito popanga ma semiconductors, ndi ma sealant pa polycrystalline silicon layers.

②Dzuwa:

Silane imagwiritsidwa ntchito popanga ma module a solar photovoltaic.

③Makampani:

Imagwiritsidwa ntchito mu Galasi Lobiriwira Losunga Mphamvu ndipo imagwiritsidwa ntchito poika filimu yopyapyala.

Phukusi lachizolowezi:

Ubwino:

①Zaka zoposa khumi pamsika;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④Magwero okhazikika a zinthu zopangira;

⑤Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑥Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;

⑦Kuyera: kalasi yamagetsi yoyera kwambiri;

⑧Kagwiritsidwe ntchito: zipangizo za maselo a dzuwa; kupanga polysilicon yoyera kwambiri, silicon oxide ndi ulusi wowala; kupanga magalasi amitundu yosiyanasiyana.
