Silane (SiH4)

Qiyaasaha Farsamada

Silane waa isku-darka silikoon iyo hydrogen.Waa erey guud oo taxane ah, oo ay ku jiraan monosilane (SiH4), disilane (Si2H6) iyo qaar ka mid ah xeryahooda silikoon-hydrogen-heer sare ah.Waxaa ka mid ah, monosilane waa kan ugu caansan, mararka qaarkood loo yaqaan silane gaaban.Silane waa gaas aan midab lahayn oo leh ur karaahiyo ah oo toon ah.Ku milmay biyaha, ku dhawaad ​​aan lagu milmi karin ethanol, ether, benzene, chloroform, chloroform silicon iyo tetrachloride silicon.Sifooyinka kiimikaad ee silanes aad bay uga firfircoon yihiin alkanes-ka oo si fudud ayaa oksaydhaysan.Gubashada degdega ahi waxay iman kartaa marka hawada la taabto.Kuma falceliso nitrogen ka hooseeya 25°C, kumana falceliso xeryahooda hydrocarbon heerkulka qolka.Dabka iyo qaraxa silane waa natiijada falcelinta ogsijiinta.Silane aad bay ugu nugul tahay ogsijiinta iyo hawada.Silane oo leh xoogaa fiirsi gaar ah ayaa sidoo kale si ba'an uga falcelinaya ogsijiinta heerkulka -180°C.Silane wuxuu noqday gaaska ugu muhiimsan ee gaarka ah ee loo isticmaalo hababka microelectronics semiconductor, waxaana loo isticmaalaa diyaarinta filimo kala duwan oo microelectronic ah, oo ay ku jiraan filimada crystal, microcrystalline, polycrystalline, silicon oxide, silicon nitride, iyo silicides bir ah.Codsiyada microelectronic ee silane ayaa wali si qoto dheer u koraya: epitaxy heerkulka hooseeya, epitaxy xulashada, iyo heteroepitaxial epitaxy.Ma aha oo kaliya qalabka silikoon iyo silikoon isku dhafan wareegyada, laakiin sidoo kale qalabka semiconductor ee isku dhafan (gallium arsenide, silicon carbide, iwm.).Waxa kale oo ay leedahay codsiyada diyaarinta agabka ceelka quantum superlatice.Waxaa la dhihi karaa in silane loo isticmaalo ku dhawaad ​​dhammaan khadadka wax soo saarka wareegga horumarsan ee casriga ah.Codsiga silane sida filim silikoon ku jira iyo daahan ayaa ka ballaartay warshadaha dhaqameed ee microelectronics ilaa meelo kala duwan sida birta, mashiinada, kiimikooyinka iyo indhaha.Codsiga kale ee suurtogalka ah ee silane waa soo saarista qaybaha mashiinka dhoobada ee waxqabadka sare leh, gaar ahaan isticmaalka silane si loo soo saaro silicide (Si3N4, SiC, iwm.) Tiknoolajiyada micropowder ayaa soo jiidatay dareen badan.

Codsiga:

①Electronik:

Silane waxaa lagu dabaqaa lakabyada silikoon ee polycrystalline on wafers silikoon marka la soo saarayo semiconductors, iyo sealants.

②Solar:

Silane waxaa loo isticmaalaa soosaarka moduleka sawir-qaadista.

③ Warshadaha:

Waxa loo istcimaalaa tamarta-badbaadinta galaaska cagaaran waxaana lagu dabaqaa kaydinta uumiga habka filimada khafiifka ah.
