Silanes inogadzirwa sei?

2023-07-12

1. Silane inogadzirwa sei?

(1) Magnesium silicide nzira: gadzirisa hupfu hwakavhenganiswa hwesilicon uye magnesium muhydrogen inenge 500 ° C, uye itai iyo yakagadzirwa magnesium silicide neammonium chloride mune yakaderera-tembiricha mvura ammonia kuwana silane. Kucheneswa kwayo mumudziyo we distillation wakatonhodzwa ne liquid nitrogen inobereka silane yakachena.
(2) Heterogeneous reaction method: react silicon powder, silicon tetrachloride uye hydrogen muvira remubhedha rinopisa rinopisa pamusoro pe500 ° C kuti riwane trichlorosilane. Trichlorosilane inoparadzaniswa ne distillation. Dichlorosilane inowanikwa nehterogeneous reaction pamberi peiyo catalyst. Iyo yakawanikwa dichlorosilane musanganiswa nesilicon tetrachloride uye trichlorosilane, saka dichlorosilane yakachena inogona kuwanikwa mushure mekuita distillation. Trichlorosilane uye monosilane anowanikwa kubva ku dichlorosilane achishandisa heterogeneous reaction catalyst. Iyo yakawanikwa monosilane inonatswa neyakadzikira-yepamusoro-kudzvanywa distillation mudziyo.
(3) Bata silicon-magnesium alloy nehydrochloric acid.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Silicon-magnesium alloy inopindirana neammonium bromide mu liquid ammonia.
(5) Kushandisa lithium aluminium hydride, lithium borohydride, nezvimwewo sevanoderedza, kuderedza tetrachlorosilane kana trichlorosilane mu ether.

2. Chii chinotangira silane?

Izvo zvigadzirwa zvekugadzirira kwesilanekunyanya silicon poda uye hydrogen. Izvo zvinodiwa zvekuchena kwesilicon poda zvakakwirira, zvinowanzosvika kupfuura 99.999%. Hydrogen zvakare inonatswa kuti ive nechokwadi chepamusoro kuchena kweiyo silane yakagadzirwa.

3. Chii chinonzi silane?

Sechitubu chegasi chinopa silicon zvikamu, silane inogona kushandiswa kugadzira yakakwirira-kuchena polycrystalline silicon, single crystal silicon, microcrystalline silicon, amorphous silicon, silicon nitride, silicon oxide, heterogeneous silicon, uye akasiyana simbi silicides. Nekuda kwekuchena kwayo kwepamusoro uye kutonga kwakanaka, yave yakakosha gasi isingagone kutsiviwa nemamwe akawanda masilicon masosi. Silane inoshandiswa zvakanyanya mumaindasitiri emicroelectronics uye optoelectronics, uye inoshandiswa mukugadzira masero ezuva, flat panel displays, girazi uye masimbi ekuputira, uye ndicho chega chigadzirwa chepakati munyika chekugadzirwa kwakakura kwegranular high-purity silicon. Iwo epamusoro-tekinoroji mashandisirwo eSilane achiri kubuda, kusanganisira kushandiswa mukugadzirwa kwemhando yepamusoro ceramics, zvinhu zvinoumbwa, zvinoshanda, biomaterials, yakakwirira-energy zvinhu, nezvimwewo, uye inova hwaro hwehuzhinji hutsva tekinoroji, zvinhu zvitsva, uye zvishandiso zvitsva.

4. Ko silanes inochengetedza zvakatipoteredza here?

Ehe, silane yekurapa mumiriri haina heavy metal ions nezvimwe zvinosvibisa, uye inoenderana neROHS uye SGS kuchengetedzwa kwezvakatipoteredza.

5. Kushandiswa kwe silane

Skeleton chimiro che chlorosilanes uye alkyl chlorosilanes, epitaxial kukura kwesilicon, mbishi zvinhu zvepolysilicon, silicon oxide, silicon nitride, nezvimwewo, masero ezuva, optical fibers, girazi remavara kugadzira, kemikari vapor deposition.
