Kev piav qhia
Silicon yog cov khoom siv tshuaj nrog lub cim Si thiab atomic tooj 14. Nws yog metalloid, txhais tau tias nws muaj cov khoom ntawm cov hlau thiab nonmetals. Txawm li cas los xij, nws feem ntau hu ua nonmetal nyob rau hauv kev tshawb fawb zej zog vim nws cov electronegativity siab thiab thermal conductivity tsawg.
Txawm hais tias raug suav hais tias yog nonmetal, silicon feem ntau siv hauv cov hlau alloys, xws li hlau thiab txhuas. Nws kuj tseem siv dav hauv kev lag luam hluav taws xob ua cov khoom tseem ceeb hauv semiconductors. Cov semiconductors no, thaum ua ke nrog lwm cov ntaub ntawv, tsim lub hauv paus rau feem ntau cov khoom siv hluav taws xob uas peb siv niaj hnub no, suav nrog khoos phis tawj, xov tooj, thiab TV.

Silicon yog qhov thib ob tshaj plaws hauv ntiaj teb, tom qab oxygen, thiab tuaj yeem pom hauv pob zeb, xuab zeb, thiab av. Nws kuj tseem muaj nyob hauv tib neeg lub cev me me thiab yog qhov tseem ceeb rau kev noj qab haus huv ntawm cov pob txha thiab cov ntaub so ntswg. Txawm li cas los xij, silicon ntau dhau tuaj yeem ua rau muaj kev phom sij thiab tau txuas rau mob ntsws cancer hauv qee qhov kev lag luam uas raug silica hmoov av ntau.
Hais txog nws lub cev lub cev, silicon yog ib qho nyuaj, nkig, thiab crystalline khoom uas yog xiav-grey xim. Nws cov ntsiab lus melting thiab boiling yog qhov siab dua piv rau lwm cov nonmetals, uas tuaj yeem raug ntaus nqi rau nws cov yam ntxwv ntawm cov hlau.
Hauv kev xaus, thaum silicon tsis yog technically ib qho hlau, nws muaj qee yam khoom siv hlau thiab feem ntau siv ua ke nrog hlau hauv ntau yam lag luam. Nws qhov tseem ceeb hauv kev lag luam hluav taws xob tsis tuaj yeem hais dhau los thiab nws qhov kev nplua nuj nyob hauv ntiaj teb ua rau nws muaj txiaj ntsig zoo rau kev tsim kho thev naus laus zis yav tom ntej.
FAQ
Q: Koj puas yog cov chaw tsim khoom lossis cov tub luam?
A: Peb yog cov chaw tsim khoom tiag tiag, peb tsis tsuas yog tuaj yeem muab cov khoom lag luam zoo nrog tus nqi zoo tshaj plaws, tab sis kuj tuaj yeem muab cov kev pabcuam zoo tshaj plaws ua ntej muag thiab kev pabcuam tomqab muag.
Q: Koj muaj cov qauv dab tsi?
A: Peb cov khoom ua tau raws li cov qauv, xws li ASTM, ASME, AMS, DIN, JIS thiab lwm yam.Qhov kev xeem thib peb yog txhua yam muaj rau peb.
Q: Koj lub sijhawm ua haujlwm yog dab tsi?
A: Feem ntau nws xav tau li ntawm 15- 20 hnub tom qab tau txais PO.
