Sidee loo soo saaraa silanes?

2023-07-12

1. Sidee loo sameeyaa silane?

(1) Habka silicide Magnesium: ka fal celi budada isku dhafan ee silikoon iyo magnesium ee hydrogen qiyaastii 500 ° C, oo ka falceli magnesium silicide ee la abuuray ammonium chloride ee heerkulka hooseeya ammonia si loo helo silane. Sifeynta ee qalabka distillation ee lagu qaboojiyey nitrogen dareere ah waxay soo saartaa silane saafi ah.
(2) Habka falcelinta kala duwan: ka fal celi budada silikoon, tetrachloride silicon iyo hydrogen foornada sariirta dareeraha leh ee kulaylaysa 500°C si aad u hesho trichlorosilane. Trichlorosilane waxaa lagu kala saaraa kala-bax. Dichlorosilane waxaa lagu helaa falcelin kala duwan marka ay jirto kiciye. Dichlorosilane-ka la helay waa isku dhafka silikoon tetrachloride iyo trichlorosilane, sidaas darteed dichlorosilane saafi ah ayaa la heli karaa ka dib marka la nadiifiyo. Trichlorosilane iyo monosilane waxaa laga helaa dichlorosilane iyadoo la adeegsanayo kicinta falcelinta kala duwan. monosilane-ka la helay waxaa lagu nadiifiyaa qalabka cadaadiska sare ee heerkulka hooseeya.
(3) Ku dawee daawaha silikoon-magnesium ee hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy waxay la falgashaa ammonium bromide ee dareeraha ammonia.
(5) Isticmaalka lithium aluminium hydride, lithium borohydride, iwm. sida hoos u dhigista wakiilada, yaree tetrachlorosilane ama trichlorosilane etherka.

2. Waa maxay alaabta laga bilaabo silane?

Qalabka ceeriin ee loogu talagalay diyaarintasilaanyowaxay u badan yihiin budada silikon iyo hydrogen. Shuruudaha nadiifka ah ee budada silikon waa kuwo aad u sarreeya, guud ahaan waxay gaaraan in ka badan 99.999%. Hydrogen sidoo kale waa la safeeyey si loo hubiyo nadiifnimada sare ee silane la diyaariyey.

3. Waa maxay shaqada silane?

Sida ilo gaas ah oo bixiya qaybaha silikon, silane waxaa loo isticmaali karaa in lagu soo saaro silikoon polycrystalline nadiif ah, silikoon hal crystal ah, silikoon microcrystalline, silicon amorphous, silicon nitride, silicon oxide, silicon heterogeneous, iyo silicides biraha kala duwan. Sababtoo ah nadiifinteeda sare iyo xakamaynta wanaagsan, waxay noqotay gaas khaas ah oo muhiim ah oo aan lagu bedeli karin ilo kale oo badan oo silikon ah. Silane waxaa si weyn loogu isticmaalaa warshadaha microelectronics iyo optoelectronics, waxaana loo isticmaalaa soo saarista unugyada cadceedda, bandhigyada guddiyada fidsan, muraayadaha iyo dahaarka birta, waana sheyga kaliya ee dhexdhexaadka ah ee adduunka wax soo saarka baaxadda weyn ee silikon nadiif ah oo sarreeya. Codsiyada teknoolajiyada sare ee silane ayaa wali soo baxaya, oo ay ku jiraan isticmaalka soo saarista dhoobada horumarsan, alaabada isku dhafan, agabka shaqada, biomaterials, agab tamarta sare leh, iwm. qalab cusub.

4. Silanes ma deegaan ahaan bay u fiican yihiin?

Haa, wakiilka daawaynta silane kuma jiraan ayoonooyinka birta culus iyo wasakh kale, waxayna u hogaansantaa ROHS iyo SGS heerarka ilaalinta deegaanka.

5. Codsiga silane

Qaab dhismeedka qalfoofka ee chlorosilanes iyo alkyl chlorosilanes, koritaanka epitaxial ee silikoon, alaabta ceeriin ee polysilicon, silicon oxide, silicon nitride, iwm, unugyada qoraxda, fiilooyinka indhaha, soo saaridda dhalooyinka midabka leh, kaydinta uumiga kiimikada.
