Silane (SiH4)

Nā ʻāpana ʻenehana

ʻO Silane kahi hui o ke silika a me ka hydrogen. He huaʻōlelo maʻamau ia no nā pūhui pūhui, me ka monosilane (SiH4), disilane (Si2H6) a me kekahi mau pūhui silicon-hydrogen kiʻekiʻe. I waena o lākou, ʻo ka monosilane ka mea maʻamau, i kekahi manawa i kapa ʻia ʻo silane no ka pōkole. He kinoea kala ʻole ʻo Silane me ka ʻala hoʻopailua o ke kāleka. Hiki ke hoʻoheheʻe ʻia i ka wai, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol, etera, benzene, chloroform, silicon chloroform a me silicon tetrachloride. ʻOi aku ka ikaika o nā waiwai kemika o nā silanes ma mua o nā alkanes a ua maʻalahi ka hoʻoheheʻe ʻia. Hiki ke hoʻopau koke ʻia ke hoʻopili ʻia me ka ea. ʻAʻole ia e hana me ka nitrogen ma lalo o 25°C, a ʻaʻole hoʻi me nā pūhui hydrocarbon ma ka lumi wela. ʻO ke ahi a me ka pahū o ka silane ka hopena o ka hopena me ka oxygen. Paʻa loa ʻo Silane i ka oxygen a me ka ea. ʻO ka Silane me kahi koʻikoʻi e pane pū me ka oxygen ma kahi mahana o -180 ° C. Ua lilo ʻo Silane i ke kinoea kūikawā nui loa i hoʻohana ʻia i nā kaʻina microelectronics semiconductor, a hoʻohana ʻia i ka hoʻomākaukau ʻana i nā kiʻiʻoniʻoni microelectronic like ʻole, me nā kiʻi ʻoniʻoni ʻoniʻoni hoʻokahi, microcrystalline, polycrystalline, silicon oxide, silicon nitride, a me nā silicides metala. Ke hoʻomohala nei nā noi microelectronic o silane i ka hohonu: epitaxy haʻahaʻa haʻahaʻa, epitaxy koho, a me ka epitaxy heteroepitaxial. ʻAʻole wale no nā mea hana silika a me nā kaapuni hoʻohui silika, akā no nā mea semiconductor pūhui (gallium arsenide, silicon carbide, etc.). Loaʻa iā ia nā noi i ka hoʻomākaukau ʻana i nā mea puna wai superlattice quantum. Hiki ke ʻōlelo ʻia ua hoʻohana ʻia ka silane i nā laina hana kaapuni holomua holomua i kēia manawa. Ua hoʻonui ʻia ka hoʻohana ʻana o silane ma ke ʻano he kiʻiʻoniʻoni a me ka uhi ʻana mai ka ʻoihana microelectronics maʻamau i nā ʻano like ʻole e like me ke kila, nā mīkini, nā kemika a me nā optics. ʻO kekahi noi kūpono o ka silane ka hana ʻana i nā ʻāpana ʻenekini seramika kiʻekiʻe, ʻoi aku ka hoʻohana ʻana i ka silane no ka hana ʻana i ka silicide (Si3N4, SiC, a me nā mea ʻē aʻe).

Noi:

①Uila:

Hoʻohana ʻia ʻo Silane i nā papa silika polycrystalline ma nā wafer silika i ka wā e hana ana i nā semiconductor, a me nā mea hoʻopaʻa.

②Solar:

Hoʻohana ʻia ʻo Silane i ka hana ʻana o ka module photovoltaic solar.

③ ʻOihana:

Hoʻohana ʻia ia i loko o ka Energy-saving Green Glass a hoʻohana ʻia i ke kaʻina hana kiʻi ʻoniʻoni lahilahi.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Ma mua o ʻumi makahiki ma ka mākeke;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable kumu kumu waiwai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;

⑦Maʻemaʻe: kiʻekiʻe maʻemaʻe uila helu;

⑧Hoʻohana: nā mea hana o ka lā; ka hana ʻana i ka polysilicon maʻemaʻe kiʻekiʻe, ka silicon oxide a me ka fiber optical; hana aniani kala.
