1. Kedu ka esi eme silane?

(1) Usoro magnesium silicide: meghachi omume agwakọta ntụ ntụ nke silicon na magnesium na hydrogen n'ihe dịka 500 Celsius, ma meghachi omume magnesium silicide emepụtara na ammonium chloride na mmiri mmiri dị ala iji nweta silane. Ọcha nke ya na distillation ngwa mma na mmiri mmiri nitrogen na-amịpụta silane dị ọcha.
(2) Usoro mmeghachi omume dị iche iche: meghachi omume silicon ntụ ntụ, silicon tetrachloride na hydrogen n'ime ọkụ akwa akwa na-ekpo ọkụ n'elu 500 Celsius iji nweta trichlorosilane. Trichlorosilane na-ekewa site na distillation. A na-enweta Dichlorosilane site na mmeghachi omume dị iche iche na ọnụnọ nke ihe na-akpata. Dichlorosilane enwetara bụ ngwakọta na silicon tetrachloride na trichlorosilane, yabụ enwere ike nweta dichlorosilane dị ọcha mgbe emechara ya. A na-enweta Trichlorosilane na monosilane site na dichlorosilane site na iji ihe mmeghachi omume dị iche iche. A na-asachapụ monosilane enwetara site na ngwaọrụ distillation dị elu nke dị ala.
(3) Jiri hydrochloric acid na-emeso silicon-magnesium alloy.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy na-emeghachi omume na ammonium bromide na mmiri mmiri amonia.
(5) Iji lithium aluminum hydride, lithium borohydride, wdg dị ka ndị na-ebelata ihe, belata tetrachlorosilane ma ọ bụ trichlorosilane na ether.

2. Kedu ihe mmalite maka silane?

The akụrụngwa maka nkwadebe nkesilanebụ tumadi silicon ntụ ntụ na hydrogen. Ihe achọrọ dị ọcha nke ntụ ntụ silicon dị elu, na-erukarị karịa 99.999%. A na-anụchakwa hydrogen iji hụ na ịdị ọcha dị elu nke silane a kwadebere.

3. Gịnị bụ ọrụ nke silane?

Dị ka isi iyi gas nke na-enye ihe ndị dị na silicon, enwere ike iji silane rụpụta silicon polycrystalline dị ọcha, otu silicon kristal, silicon microcrystalline, silicon amorphous, silicon nitride, silicon oxide, silicon heterogeneous, na silicides metal dị iche iche. N'ihi ịdị ọcha ya dị elu na njikwa dị mma, ọ ghọwo gas pụrụ iche nke na-enweghị ike dochie ya site na ọtụtụ isi mmalite silicon ndị ọzọ. A na-eji Silane eme ihe n'ọtụtụ ebe na microelectronics na ụlọ ọrụ optoelectronics, a na-ejikwa ya na-emepụta mkpụrụ ndụ anyanwụ, ihe ngosi panel panel, iko na mkpuchi nchara, ọ bụkwa naanị ngwaahịa dị n'etiti ụwa maka nnukwu mmepụta nke silicon granular dị ọcha. Ngwa ngwa teknụzụ dị elu nke silane ka na-apụta, gụnyere iji na-emepụta ceramics dị elu, ihe mejupụtara ihe mejupụtara, ihe arụ ọrụ, biomaterials, ihe ndị nwere ike dị elu, wdg, wee bụrụ ihe ndabere nke ọtụtụ teknụzụ ọhụrụ, ihe ọhụrụ, na ngwaọrụ ọhụrụ.

4. Silanes ọ bụ enyi na enyi gburugburu ebe obibi?

Ee, onye na-ahụ maka ọgwụgwọ silane enweghị ion metal dị arọ na mmetọ ndị ọzọ, yana ọ na-agbaso ụkpụrụ nchekwa gburugburu ROHS na SGS.

5. Ngwa nke silane

Ọdịdị skeleton nke chlorosilanes na alkyl chlorosilanes, uto epitaxial nke silicon, akụrụngwa nke polysilicon, silicon oxide, silicon nitride, wdg, sel anyanwụ, eriri anya, imepụta iko nwere agba, ntinye kemịkalụ.
