Akhiwa kanjani ama-silane?
(1) Indlela ye-Magnesium silicide: phendula impushana exubile ye-silicon ne-magnesium ku-hydrogen cishe ku-500°C, futhi usabele i-silicidi ye-magnesium ekhiqiziwe ne-ammonium chloride ku-ammonia ewuketshezi enezinga eliphansi lokushisa ukuze uthole i-silane. Ukuyihlanza emshinini wokucwilisa amanzi opholile nge-nitrogen ewuketshezi kuveza i-silane ehlanzekile.
(2) Indlela yokusabela ehlukahlukene: phendula i-silicon powder, i-silicon tetrachloride ne-hydrogen esithandweni sombhede esimanzi esishiswe ngaphezu kuka-500°C ukuze kutholwe i-trichlorosilane. I-Trichlorosilane ihlukaniswa yi-distillation. I-Dichlorosilane itholakala ngokusabela okungafani phambi kwe-catalyst. I-dichlorosilane etholakele iyingxube ne-silicon tetrachloride kanye ne-trichlorosilane, ngakho-ke i-dichlorosilane ehlanzekile ingatholakala ngemva kokukhishwa kwe-distillation. I-Trichlorosilane ne-monosilane atholakala ku-dichlorosilane kusetshenziswa i-heterogeneous reaction catalyst. I-monosilane etholiwe ihlanzwa ngedivayisi yokushisa ephansi ye-high-pressure distillation.
(3) Phatha ingxubevange ye-silicon-magnesium nge-hydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Ingxubevange ye-silicon-magnesium ihlangana ne-ammonium bromide ku-ammonia ewuketshezi.
(5) Ukusebenzisa i-lithium aluminium hydride, i-lithium borohydride, njll njengama-ejenti okunciphisa, nciphisa i-tetrachlorosilane noma i-trichlorosilane ku-ether.
2. Ithini into yokuqala ye-silane?
Izinto zokusetshenziswa zokulungiselelasilaneikakhulukazi i-silicon powder ne-hydrogen. Izidingo zokuhlanzeka kwe-silicon powder ziphakeme kakhulu, ngokuvamile zifinyelela ngaphezu kwe-99.999%. I-Hydrogen nayo iyacwengwa ukuze kuqinisekiswe ukuhlanzeka okuphezulu kwe-silane elungisiwe.
3. Uyini umsebenzi we-silane?
Njengomthombo wegesi ohlinzeka ngezingxenye ze-silicon, i-silane ingasetshenziswa ukwenza i-silicon ye-polycrystalline ephezulu-purity, i-silicon eyodwa yekristalu, i-silicon ye-microcrystalline, i-amorphous silicon, i-silicon nitride, i-silicon oxide, i-silicon ehlukahlukene, kanye nezinsimbi ezihlukahlukene zensimbi. Ngenxa yokuhlanzeka kwayo okuphezulu nokulawula okuhle, isiphenduke igesi ekhethekile ekhethekile engakwazi ukushintshwa eminye imithombo eminingi ye-silicon. I-Silane isetshenziswa kakhulu ezimbonini zama-microelectronics kanye nezimboni ze-optoelectronics, futhi isetshenziswa ekwenzeni amaseli elanga, izibonisi zamaphaneli ayisicaba, ingilazi nezingubo zensimbi, futhi iwukuphela komkhiqizo omaphakathi emhlabeni wokukhiqiza ngezinga elikhulu i-silicon ye-granular high-purity. Izicelo zobuchwepheshe obuphezulu be-silane zisavela, okuhlanganisa ukusetshenziswa ekwenziweni kwezitsha zobumba ezithuthukisiwe, izinto eziyinhlanganisela, izinto zokusebenza, ama-biomaterials, izinto ezisebenza ngamandla amakhulu, njll., futhi zibe yisisekelo sobuchwepheshe obuningi obusha, izinto ezintsha, kanye amadivaysi amasha.
4. Ingabe ama-silane ahambisana nemvelo?
Yebo, i-ejenti yokwelapha i-silane ayiqukethe ama-ion ensimbi esindayo nokunye ukungcola, futhi ithobela i-ROHS kanye nezindinganiso zokuvikela imvelo ze-SGS.
5. Ukusetshenziswa kwe-silane
Isakhiwo se-skeleton se-chlorosilanes ne-alkyl chlorosilanes, ukukhula kwe-epitaxial kwe-silicon, izinto zokusetshenziswa ze-polysilicon, i-silicon oxide, i-silicon nitride, njll.
ungakwazi ukuphuza i-liquid carbon dioxide?
