1. Yenziwa njani i-silane?

(1) Indlela ye-Magnesium silicide: phendula i-powder edibeneyo ye-silicon kunye ne-magnesium kwi-hydrogen malunga ne-500 ° C, kwaye iphendule i-silicid ye-magnesium eyenziwe nge-ammonium chloride kwi-low-temperature liquid ammonia ukufumana i-silane. Ukucocwa kwayo kwisixhobo sokuxutywa kwe-distillation epholile ngenitrogen engamanzi ivelisa i-silane esulungekileyo.
(2) Indlela yokusabela okungafaniyo: phendula i-silicon powder, i-silicon tetrachloride kunye ne-hydrogen kwisithando somlilo esivuthayo esishushu ngaphezu kwe-500 ° C ukufumana i-trichlorosilane. I-Trichlorosilane yohlulwe nge-distillation. I-Dichlorosilane ifumaneka ngokusabela okungafaniyo kubukho be-catalyst. I-dichlorosilane efunyenweyo ngumxube kunye ne-silicon tetrachloride kunye ne-trichlorosilane, ngoko ke i-dichlorosilane ecocekileyo inokufumaneka emva kwe-distillation. I-Trichlorosilane kunye ne-monosilane zifumaneka kwi-dichlorosilane kusetyenziswa i-heterogeneous reaction catalyst. I-monosilane efunyenweyo ihlanjululwe ngumgangatho ophantsi wokushisa okuphezulu kwe-distillation device.
(3) Phatha i-silicon-magnesium alloy kunye ne-hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) I-silicon-magnesium alloy isabela kunye ne-ammonium bromide kwi-ammonia yolwelo.
(5) Ukusebenzisa i-lithium aluminium hydride, i-lithium borohydride, njl. njengama-agent okunciphisa, ukunciphisa i-tetrachlorosilane okanye i-trichlorosilane kwi-ether.

2. Yeyiphi imathiriyeli yokuqala ye-silane?

Iimathiriyeli ekrwada ukulungiselelasilaneubukhulu becala zingumgubo wesilicon kunye nehydrogen. Iimfuno zokucoceka kwe-silicon powder ziphezulu, ngokubanzi zifikelela ngaphezu kwe-99.999%. I-Hydrogen iphinda icocwe ukuqinisekisa ukucoceka okuphezulu kwe-silane elungisiweyo.

3. Yintoni umsebenzi wesilene?

Njengomthombo wegesi obonelela ngamacandelo e-silicon, i-silane ingasetyenziselwa ukwenza i-silicon ecocekileyo ye-polycrystalline, i-silicon eyodwa ye-crystalline, i-silicon ye-microcrystalline, i-silicon ye-amorphous, i-silicon nitride, i-silicon oxide, i-silicon engafaniyo, kunye ne-silicone ezahlukeneyo zetsimbi. Ngenxa yokucoceka kwayo okuphezulu kunye nolawulo oluhle, iye yaba yigesi ekhethekileyo ekhethekileyo engenakutshintshwa yimithombo emininzi ye-silicon. I-Silane isetyenziswa kakhulu kumashishini e-microelectronics kunye ne-optoelectronics, kwaye isetyenziselwa ukuveliswa kweeseli zelanga, imiboniso yepaneli eyisicaba, iglasi kunye neengubo zentsimbi, kwaye kuphela kwemveliso ephakathi ehlabathini kwimveliso emikhulu ye-silicone ye-granular high-purity. Ukusetyenziswa kobuchwephesha obuphezulu be-silane zisavela, kubandakanywa ukusetyenziswa ekwenzeni iiseramikhi eziphambili, imathiriyeli ehlanganisiweyo, imathiriyeli esebenzayo, i-biomaterials, imathiriyeli yamandla aphezulu, njl. njl., kwaye ibe sisiseko sobuchwephesha obuninzi obutsha, imathiriyeli entsha, kunye izixhobo ezitsha.

4. Ingaba iisileni zihambelana nokusingqongileyo?

Ewe, i-agent yonyango ye-silane ayinayo i-ion yensimbi enzima kunye nezinye izinto ezingcolileyo, kwaye ihambelana ne-ROHS kunye nemigangatho yokukhusela i-SGS.

5. Ukusetyenziswa kwe-silane

Ukwakhiwa kweSkeleton ye-chlorosilanes kunye ne-alkyl chlorosilanes, ukukhula kwe-epitaxial ye-silicon, izinto eziluhlaza ze-polysilicon, i-silicon oxide, i-silicon nitride, njl.
