tlhophiso ea tšepe ea silicon

Karolelano ea tšepe ea silicon hangata e hlophisoa ka litaba tsa litšila tse tharo tse kholo tsa tšepe, aluminium le calcium tse fumanehang sebopehong sa tšepe sa silicon. Ho ea ka litaba tsa tšepe, aluminium le k'halsiamo ka silicon ea tšepe, silicon ea tšepe e ka aroloa ka 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 le lihlopha tse ling tse fapaneng.

Ka indasteri, silicon ea tšepe hangata e hlahisoa ke phokotso ea carbon ea silicon dioxide ka liboping tsa motlakase. Chemical reaction equation: SiO2 + 2C → Si + 2CO Ho hloeka ha silicon e hlahisoang ka tsela ena ke 97 ~ 98%, e bitsoang metallic silicon. Ebe e qhibiliha ebe e tsosolosoa hape, 'me litšila li tlosoa ka acid ho fumana silicon ea tšepe e nang le bohloeki ba 99.7 ~ 99.8%.

Silicon tšepe haholo-holo e entsoe ka silicon, kahoo e na le thepa e tšoanang le ea silicon. Silicon e na le li-allotrope tse peli: silicon ea amorphous le silicon ea kristale. Amorphous silicon ke phofo e bohlooho-botšo 'me ha e le hantle ke microcrystal. Silicon ea kristale e na le sebopeho sa kristale le thepa ea semiconductor ea daemane, ntlha e qhibilihang 1410 ℃, ntlha e belang 2355 ℃, Mohs hardness 7, brittle. Amorphous sililicification e sebetsa 'me e ka chesa ka matla ka oksijene. E sebetsana le dimetale tse kang halogens, naetrojene le khabone mochesong o phahameng, mme e ka boela ya kopana le dimetale tse kang magnesium, calcium le iron ho hlahisa silicide. Silicon ea amorphous e batla e sa qhibilihe ka har'a li-inorganic le organic acid, ho kenyeletsoa hydrofluoric acid, empa e qhibiliha ka acid e tsoakiloeng ea asiti ea nitric le hydrofluoric acid. Tharollo e tebileng ea sodium hydroxide e ka qhala silicon ea amorphous mme ea lokolla hydrogen. Silicone ea crystalline e batla e sa sebetse, esita le ka mocheso o phahameng ha o kopane le oksijene, ha e qhibilihe ka har'a li-inorganic le organic acid, empa e qhibiliha ka acid ea nitric le hydrofluoric acid e tsoakiloeng le tharollo e tebileng ea sodium hydroxide.
