1. Pehea i hana ʻia ai ka silane?

(1) ʻO ke ʻano o ka magnesium silicide: e hoʻopili i ka pauka hui ʻia o ke silikoni a me ka magnesium i loko o ka hydrogen ma kahi o 500 ° C, a e hana i ka silicide magnesium i hana ʻia me ka ammonium chloride i loko o ka haʻahaʻa haʻahaʻa wai amonia e loaʻa ai ka silane. ʻO ka hoʻomaʻemaʻe ʻana iā ia i loko o kahi mea hoʻoheheʻe i hoʻomaloʻo ʻia me ka wai nitrogen e loaʻa ai ka silane maʻemaʻe.
(2) Heterogeneous reaction method: hoʻopili i ka pauka silika, silicon tetrachloride a me ka hydrogen i loko o ka umu i hoʻoheheʻe ʻia ma luna o 500°C no ka loaʻa ʻana o trichlorosilane. Hoʻokaʻawale ʻia ʻo Trichlorosilane e ka distillation. Loaʻa ka Dichlorosilane ma ka hopena heterogeneous i mua o kahi catalyst. ʻO ka dichlorosilane i loaʻa he hui pū me ka silicon tetrachloride a me trichlorosilane, no laila hiki ke loaʻa ka dichlorosilane maʻemaʻe ma hope o ka distillation. Loaʻa ʻia ka trichlorosilane a me ka monosilane mai ka dichlorosilane me ka hoʻohana ʻana i kahi catalyst hopena heterogeneous. Hoʻomaʻemaʻe ʻia ka monosilane i loaʻa e kahi mea hoʻoheheʻe haʻahaʻa haʻahaʻa haʻahaʻa.
(3) E mālama i ka huila silicon-magnesium me ka waika hydrochloric.
Mg2Si+4HCl—→2MgCl2+SiH4
(4) Hoʻopili ka silikon-magnesium alloy me ka ammonium bromide i loko o ka ammonia wai.
(5) Ke hoʻohana nei i ka lithium aluminum hydride, lithium borohydride, a me nā mea ʻē aʻe e like me nā mea hoʻohaʻahaʻa, e hoʻemi i ka tetrachlorosilane a i ʻole trichlorosilane i ka ether.

2. He aha ka mea hoʻomaka no ka silane?

ʻO nā mea maka no ka hoʻomākaukau ʻana osilaneʻO ka nui o ka pauka silika a me ka hydrogen. ʻO nā koi maʻemaʻe o ka pauka silika he kiʻekiʻe, ʻoi aku ka nui ma mua o 99.999%. Hoʻomaʻemaʻe ʻia ka hydrogen e hōʻoia i ka maʻemaʻe kiʻekiʻe o ka silane i hoʻomākaukau ʻia.

3. He aha ka hana o ka silane?

Ma ke ʻano he kumu kinoea e hāʻawi ana i nā ʻāpana silika, hiki ke hoʻohana ʻia ka silane no ka hana ʻana i ke silikoni polycrystalline maʻemaʻe kiʻekiʻe, ke silika aniani hoʻokahi, ke silikika microcrystalline, ke kilika amorphous, ka silicon nitride, ka silicon oxide, ka silika heterogeneous, a me nā silicides metala like ʻole. Ma muli o kona maʻemaʻe kiʻekiʻe a me ka mana maikaʻi, ua lilo ia i kinoea kūikawā koʻikoʻi ʻaʻole hiki ke pani ʻia e nā kumu silika ʻē aʻe. Hoʻohana nui ʻia ʻo Silane i nā ʻoihana microelectronics a me optoelectronics, a hoʻohana ʻia i ka hana ʻana i nā cell solar, flat panel displays, aniani a me ke kila kila, a ʻo ia wale nō ka huahana waena o ka honua no ka hana nui ʻana o ka granular high-purity silicon. Ke puka mai nei nā ʻenehana kiʻekiʻe o ka silane, me ka hoʻohana ʻana i ka hana ʻana i nā seramika kiʻekiʻe, nā mea hoʻohuihui, nā mea hana, nā biomaterials, nā mea ikaika kiʻekiʻe, a me nā mea ʻē aʻe, a lilo i kumu o nā ʻenehana hou he nui, nā mea hou, a mea hou.

4. He maikaʻi anei nā silanes?

ʻAe, ʻaʻole i loaʻa i ka lāʻau lapaʻau silane nā ion metala kaumaha a me nā mea haumia ʻē aʻe, a ua hoʻokō ʻo ia i nā kūlana palekana kaiapuni ROHS a me SGS.

5. Hoʻohana i ka silane

ʻO ka hana iwi o nā chlorosilanes a me nā alkyl chlorosilanes, ka ulu ʻana o ka epitaxial o ke silika, nā mea maka o ka polysilicon, silicon oxide, silicon nitride, a me nā mea ʻē aʻe.
