  • Te whakarōpū whakarewa Silicon

    Te nuinga o te wa ka whakarōpūhia te whakarewa Silicon i runga i te ihirangi o te rino, te konumohe me te konupūmā, ko nga poke matua e toru kei roto i te hanganga whakarewa silicon.E ai ki te ihirangi o te rino, te konumohe me te konupūmā i roto i te whakarewa silicon, ka taea te wehea te whakarewa silicon ki te 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 me etahi atu tohu rereke.

    I roto i te ahumahi, he mea hanga te konganuku silicon ma te whakaiti i te hauhautanga silicon mai i te waro i roto i te oumu hiko.Te whārite tauhohenga matū: SiO2 + 2C → Si + 2CO kia 97~98% te parakore o te silicon, e kiia ana ko te whakarewa silicon.I muri rewa, recrystallization, poke tango ki te waikawa, te ma o 99.7 ~ 99.8% silicon whakarewa i whiwhi.

    Ko te konutara Silicon te nuinga o te silicon, no reira he rite nga ahuatanga ki te silicon.E rua nga allotropes o te silicon amorphous me te silicon crystalline.Ko te silicon Amorphous he paura hina-pango he microcrystal tonu.Ko te silicon Crystalline te hanganga karaihe me nga ahuatanga semiconductor o taimana, ira whakarewa 1410 ℃, ira kohua 2355 ℃, kiato 2.32 ~ 2.34 g/cm 3, Mohs pakeke 7, pakarukaru.Ko te silicification amorphous he matū kaha, ka kaha te wera i roto i te hāora.Ka taea e ia te tauhohe ki nga konganuku kore penei i te halogen, te hauota me te waro i te pāmahana teitei, ka taea hoki te tauhohe ki nga konganuku penei i te konupora, te konupūmā me te rino ki te whakaputa silicides.Ko te silicon Amorphous he tata kore e rewa i roto i nga waikawa pararopi me te waikawa waro katoa, tae atu ki te waikawa pukoro, engari ka whakarewahia ki te ranunga o te waikawa nitric me te waikawa waiwaro.Ka taea e te wairewa konutai konutai te whakakorikori i te silicon amorphous me te tuku hau hauwai.He hohekore te kirikiri kiriata, karekau e ngotea ki te hāora ahakoa te wera nui.Kare e rewa i roto i nga momo waikawa pararopi me te waikawa waro, engari ka whakarewahia i roto i te ranunga o te waikawa nitric me te waikawa waiwaro me te wairewa konutai konutai.
