Silane ni iki?

Silaneni uruvange rwa silicon na hydrogen, kandi ni ijambo rusange ryuruhererekane rwibintu. Silane ikubiyemo ahanini monosilane (SiH4), disilane (Si2H6) hamwe na hydrogène yo mu rwego rwo hejuru yo mu rwego rwo hejuru, hamwe na formula rusange SinH2n + 2. Ariko, mubikorwa nyabyo, muri rusange tuvuga monosilane (formula ya chimique SiH4) nka "silane".

Urwego rwa elegitoronikigazi ya silaneiboneka cyane muburyo butandukanye bwo gutandukanya no kweza ifu ya silicon, hydrogen, silicon tetrachloride, catalizator, nibindi. Silane ifite ubuziranenge bwa 3N kugeza 4N yitwa silane yo mu rwego rwinganda, na silane ifite ubuziranenge burenga 6N yitwa electron- gazi ya silane.

Nka soko ya gaze yo gutwara ibice bya silicon,gazi ya silaneyahindutse gaze idasanzwe idashobora gusimburwa nandi masoko menshi ya silikoni kubera ubuziranenge bwayo nubushobozi bwo kugera kugenzura neza. Monosilane itanga silikoni ya kristaline binyuze muri reaction ya pyrolysis, kuri ubu ikaba ari bumwe mu buryo bwo gukora umusaruro munini wa silicon ya monocrystalline na silicon polycrystalline ku isi.

Ibiranga Silane

Silane (SiH4)ni gaze itagira ibara ifata umwuka kandi igatera guhumeka. Ijambo ryayo ni silicon hydride. Imiti yimiti ya silane ni SiH4, kandi ibiyirimo biri hejuru ya 99,99%. Ku bushyuhe bwicyumba nigitutu, silane ni gaze yubumara mbi. Gushonga kwa silane ni -185 ℃ naho guteka ni -112 ℃. Ku bushyuhe bwicyumba, silane irahagaze, ariko iyo ishyutswe kugeza 400 ℃, izangirika rwose muri silicon ya gaze na hydrogen. Silane irashya kandi iraturika, kandi izashya mu kirere cyangwa gaze ya halogene.

Imirima yo gusaba

Silane ifite uburyo bwinshi bwo gukoresha. Usibye kuba aribwo buryo bwiza bwo guhuza molekile ya silikoni hejuru y’akagari mu gihe cyo gukora imirasire y'izuba, inakoreshwa cyane mu nganda zikora nka semiconductor, icyerekezo kibase, hamwe nikirahure.

Silaneni isoko ya silicon kubikorwa byo guta imyuka ya chimique nka silikoni imwe ya kirisiti imwe, polifisstalline silicon epitaxial wafers, silicon dioxyde, nitride ya silicon, hamwe nikirahure cya fosifosilike munganda zikoresha imashanyarazi, kandi ikoreshwa cyane mugukora no guteza imbere ingirabuzimafatizo zuba, ingoma ya silicon copier ingoma , ibyuma bifata amashanyarazi, fibre optique, nikirahure kidasanzwe.

Mu myaka yashize, tekinoroji yo mu rwego rwo hejuru ya silan iracyagaragara, harimo gukora ubukorikori bugezweho, ibikoresho bikomatanya, ibikoresho bikora, biomaterial, ibikoresho bitanga ingufu nyinshi, nibindi, bikaba ishingiro ryikoranabuhanga rishya, ibikoresho bishya, nibishya ibikoresho.
