Li-silane li etsoa joang?
(1) Magnesium silicide mokhoa: itšoara ka phofo e tsoakiloeng ea silicon le magnesium ka hydrogen hoo e ka bang 500 ° C, 'me u sebetsane le silicide ea magnesium e entsoeng ka ammonium chloride ka ammonia ea metsi a tlaase a mocheso ho fumana silane. Ho hloekisoa ha eona ka sesebelisoa sa distillation se pholileng ka metsi a naetrojene e hlahisa silane e hloekileng.
(2) Heterogeneous reaction method: itšoara joang ka silicon powder, silicon tetrachloride le hydrogen ka seboping sa bethe se nang le metsi se futhumetseng ka holimo ho 500 ° C ho fumana trichlorosilane. Trichlorosilane e arotsoe ke distillation. Dichlorosilane e fumanoa ka karabelo e fapaneng ka boteng ba catalyst. Dichlorosilane e fumanoeng ke motsoako o nang le silicon tetrachloride le trichlorosilane, kahoo dichlorosilane e hloekileng e ka fumanoa ka mor'a distillation. Trichlorosilane le monosilane li fumanoa ho tsoa ho dichlorosilane ho sebelisoa motsoako o fapaneng oa karabelo. Monosilane e fumanoeng e hloekisoa ka mocheso o tlase oa mocheso o phahameng oa khatello ea mocheso.
(3) Tšoara motsoako oa silicon-magnesium ka hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy e sebetsana le ammonium bromide ho ammonia ea metsi.
(5) Ho sebelisa lithium aluminium hydride, lithium borohydride, joalo-joalo e le lisebelisoa tse fokotsang, fokotsa tetrachlorosilane kapa trichlorosilane ka ether.
2. Thepa e qalang ea silane ke efe?
Thepa e tala bakeng sa ho lokisetsa easilanehaholo-holo ke phofo ea silicon le hydrogen. Litlhoko tsa bohloeki tsa phofo ea silicon li batla li phahame, ka kakaretso li fihla ho feta 99.999%. Hydrogen e boetse e hloekisoa ho netefatsa bohloeki bo phahameng ba silane e lokisitsoeng.
3. Mosebetsi oa silane ke ofe?
E le mohloli oa khase o fanang ka likarolo tsa silicon, silane e ka sebelisoa ho etsa polycrystalline silicon e phahameng-e hloekileng, silicon e le 'ngoe ea kristale, silicon ea microcrystalline, silicon ea amorphous, silicon nitride, silicon oxide, silicon e fapaneng, le li-silicone tse sa tšoaneng tsa tšepe. Ka lebaka la bohloeki bo phahameng le taolo e ntle, e fetohile khase ea bohlokoa e khethehileng e ke keng ea nkeloa sebaka ke mehloli e meng e mengata ea silicon. Silane e sebelisoa haholo liindastering tsa microelectronics le optoelectronics, 'me e sebelisoa ha ho etsoa lisele tsa letsatsi, li-panels tse bataletseng, likhalase le litšepe tsa tšepe,' me ke sehlahisoa se le seng feela sa lipakeng lefatšeng bakeng sa tlhahiso e kholo ea silicon e phahameng ea granular. Lisebelisoa tsa theknoloji e phahameng tsa silane li ntse li hlaha, ho kenyelletsa le tšebeliso ea ho etsa lirafshoa tse tsoetseng pele, lisebelisoa tse kopantsoeng, lisebelisoa tse sebetsang, biomaterials, lisebelisoa tse nang le matla a phahameng, joalo-joalo, 'me e fetoha motheo oa mekhoa e mengata e mecha, lisebelisoa tse ncha le lisebelisoa tse ncha.
4. Na li-silane li baballa tikoloho?
E, moemeli oa phekolo ea silane ha a na li-ion tsa tšepe tse boima le lintho tse ling tse silafatsang, 'me o lumellana le litekanyetso tsa ts'ireletso ea tikoloho ea ROHS le SGS.
5. Tšebeliso ea silane
Sebopeho sa skeleton sa chlorosilanes le alkyl chlorosilanes, kholo ea epitaxial ea silicon, lisebelisoa tse tala tsa polysilicon, silicon oxide, silicon nitride, joalo-joalo, lisele tsa letsatsi, likhoele tsa optical, tlhahiso ea likhalase tse mebala, ho beha mouoane oa lik'hemik'hale.
