SilaneHe hui ia o ke kilikaka a me ka hydrogen, a he hua'ōlelo maʻamau no ka pūʻulu o nā pūhui. ʻO ka nui o ka Silane ka monosilane (SiH4), disilane (Si2H6) a me kekahi mau pūhui hydrogen silika kiʻekiʻe, me ke ʻano maʻamau SinH2n+2. Eia nō naʻe, i ka hana maoli ʻana, ʻōlelo mākou i ka monosilane (kemimi formula SiH4) ma ke ʻano he "silane".

Papa uilakinoea silaneloaʻa nui ʻia e nā ʻano like ʻole o ka distillation a me ka hoʻomaʻemaʻe ʻana i ka pauka silika, hydrogen, silicon tetrachloride, catalyst, etc. grade silane gas.

Ma ke ʻano he kumu kinoea no ka lawe ʻana i nā ʻāpana silika,kinoea silaneua lilo i kinoea koʻikoʻi koʻikoʻi ʻaʻole hiki ke hoʻololi ʻia e nā kumu silika ʻē aʻe no kona maʻemaʻe kiʻekiʻe a hiki ke hoʻokō i ka mana maikaʻi. Hoʻokumu ʻo Monosilane i ke silika crystalline ma o ka hopena pyrolysis, ʻo ia kekahi o nā ala no ka hana nui o ka silikon monocrystalline granular a me ka silikon polycrystalline i ka honua.

ʻO nā hiʻohiʻona Silane

Silane (SiH4)he kinoea waihoʻoluʻu ʻole e hoʻopili me ka ea a hoʻohuehu. ʻO kona ʻano like ʻole he silicon hydride. ʻO ke ʻano kemika o ka silane ʻo SiH4, a ʻo kona ʻike e like me 99.99%. Ma ka lumi wela a me ke kaomi, he kinoea ʻawaʻawa ʻo silane. ʻO ka helu hoʻoheheʻe o ka silane he -185 ℃ a ʻo ka helu hoʻolapalapa he -112 ℃. Ma ka lumi wela, paʻa ka silane, akā i ka wā i wela ai i 400 ℃, e hoʻoheheʻe loa ia i loko o ke kinoea kinoea a me ka hydrogen. Hiki ke puhi a pahū ʻo Silane, a e ʻā ia i ka ea a i ʻole ke kinoea halogen.

Nā kahua noi

He nui ka hoʻohana ʻana o Silane. Ma waho aʻe o ke ala maikaʻi loa e hoʻopili ai i nā molekala silika i ka ʻili o ke kelepona i ka wā o ka hana ʻana o nā cell solar, ua hoʻohana nui ʻia i nā mea kanu hana e like me nā semiconductor, nā hōʻike papa pālahalaha, a me ke aniani uhi.

SilaneʻO ia ke kumu silika no nā kaʻina hana hoʻoheheʻe kino e like me ka silika kristal hoʻokahi, nā wafers epitaxial silicon polycrystalline, silicon dioxide, silicon nitride, a me ke aniani phosphosilicate i ka ʻoihana semiconductor, a hoʻohana nui ʻia i ka hana ʻana a me ka hoʻomohala ʻana o nā cell solar, silicon copier drums. , nā meaʻike kiʻi kiʻi, nā fiber optical, a me ke aniani kūikawā.

I kēia mau makahiki i hala iho nei, ke puka mai nei nā noi ʻenehana kiʻekiʻe o nā silanes, me ka hana ʻana i nā seramika kiʻekiʻe, nā mea i hoʻohui ʻia, nā mea hana, nā biomaterials, nā mea ikaika kiʻekiʻe, a me nā mea ʻē aʻe, lilo i kumu o nā ʻenehana hou he nui, nā mea hou, a me nā mea hou. nā mea hana.
