Cov Khoom Ntawm Silicon Hlau

Silicon yog ib qho ntawm cov semi{0}}hlau, yav tas los hu ua "silicon". Lub melting point yog 1420℃thiab qhov ceev yog 2.34g / cm3. Nyuaj thiab nkig. Nws yog insoluble nyob rau hauv acid nyob rau hauv chav tsev kub thiab 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 qhov 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. Muaj ob lub allotropes ntawm silicon: ib qho yog xim av tsaus nti amorphous hmoov, uas ua haujlwm 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 iav thiab lwm yam khoom siv hauv tsev, thiab siab - zoo quartz yog siv los ua alloys, hlau thiab ib leeg muaju.
