Khoom Description
Silicon yog ib qho ntawm cov semi-metals, yav tas los hu ua "silicon". Lub melting point yog 1420 degree thiab qhov ceev yog 2.34g / cm3. Nyuaj thiab nkig. Insoluble nyob rau hauv acid nyob rau hauv chav tsev kub, yooj yim soluble nyob rau hauv alkali. Cov khoom ntawm hlau silicon zoo ib yam li cov germanium, txhuas, thiab tin, thiab muaj cov khoom semiconductor. Silicon yog nplua nuj nyob rau hauv lub ntiaj teb crust, thib ob tsuas yog oxygen, suav txog ntau tshaj li ib feem peb ntawm tag nrho cov hnyav ntawm lub ntiaj teb crust, thiab muaj nyob rau hauv daim ntawv ntawm silica los yog silicate. Lub purest silicon mineral yog quartz los yog silica. Silicon muaj ob lub allotropes: ib qho yog xim av tsaus amorphous hmoov, uas yog reactive thiab tuaj yeem hlawv hauv huab cua; lwm yam yog siv lead ua ruaj khov (crystalline silicon). Feem ntau, silica thiab quartz yog siv rau hauv iav thiab lwm yam khoom siv hauv tsev, thiab cov khoom siv zoo quartz yog siv los ua cov alloys, hlau thiab ib leeg muaju.
Silicon yog siv nyob rau hauv ntau kom smelt ferrosilicon alloy raws li ib tug alloying caij nyob rau hauv lub steel kev lag luam thiab raws li ib tug txo tus neeg sawv cev nyob rau hauv lub smelting ntawm ntau hlau.Silicon hlauNws tseem yog ib qho khoom zoo hauv aluminium alloys, thiab feem ntau cam khwb cia txhuas alloys muaj silicon. Silicon yog cov khoom siv raw rau ultrapure silicon hauv kev lag luam hluav taws xob. Cov khoom siv hluav taws xob ua los ntawm ultrapure semiconductor ib leeg siv lead ua silicon muaj qhov zoo ntawm qhov me me, lub teeb yuag, kev ntseeg tau zoo thiab lub neej ntev. High-power transistors, rectifiers thiab hnub ci hlwb ua los ntawm silicon ib leeg muaju doped nrog cov cim tshwj xeeb ntawm impurities yog zoo dua li cov uas ua los ntawm germanium ib leeg muaju. Kev tshawb fawb ntawm amorphous silicon hnub ci hlwb tau nce sai, thiab kev hloov pauv tau mus txog ntau dua 8%. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm silicon molybdenum pas nrig hluav taws xob cua sov lub caij muaj peev xwm ncav cuag 1700 degree, thiab nws kuj tsis yooj yim rau hnub nyoog thiab muaj zoo anti-oxidation zog. Trichlorosilane ua los ntawm silicon tuaj yeem siv los npaj ntau pua cov roj ntsha silicone thiab cov dej tsis sib haum.
