Muaj silicon yog cov khoom siv tseem ceeb tshaj plaws rau kev tsim cov organic silicon thiab polycrystalline silicon, thiab tseem yog cov khoom siv raw rau cam khwb cia aluminium alloys thiab deformed aluminium alloys.
Si Hlau
Kev lag luam silicon yog tsaus grey thiab muaj xim hlau luster. Txawm hais tias nws zoo li cov hlau, nws pom ntau cov khoom tsis yog xim hlau hauv cov tshuaj tiv thaiv. Nws conductivity yog nruab nrab ntawm cov hlau thiab tsis yog hlau. Nws feem ntau hu ua semi-hlau, uas yog, semiconductor khoom. Silicon yog tsis-conductive hauv qab 650 degree thiab tuaj yeem siv los ua cov khoom siv insulating; Nws pib ua hluav taws xob thaum nws siab tshaj 650 degree, thiab nws cov conductivity tseem nce ntxiv thaum qhov kub nce. Lub melting point ntawm silicon yog 1683 degree, lub boiling point yog 2628 degree, thiab qhov ceev yog 2330 kg / m³.
