Taw qhia ntawm silicon hlau
Hais txog nws daim ntawv thov, nws yog xim hlau silicon ua lub luag haujlwm tseem ceeb hauv kev lag luam. Hauv kev lag luam txhuas, nws yog ntxiv rau aluminium alloys los txhim kho lub zog, hardness, thiab casting kev ua haujlwm ntawm cov khoom txhuas. Qhov no ua rau alloys ntau haum rau kev tsim khoom lag luam hauv kev lag luam thiab aerospace kev lag luam. Hauv kev lag luam hluav taws xob, siab - kev coj dawb huv yog xim silica yog cov khoom siv tseem ceeb rau kev tsim cov sicemonductor wafers. Cov wafers yog lub hauv paus rau kev tsim khoom ntau yam xws li cov khoom siv hluav taws xob, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob xws li smartphones, computers, thiab ntsiav tshuaj.
Cov txheej txheem ntau lawm ntawm cov khoom siv ntawm cov hlau silicon feem ntau koom nrog smelting silica (sitio₂) nrog txo cov neeg sawv cev hauv lub tshuab hluav taws xob hauv hluav taws xob kub. Thaum lub sijhawm cov txheej txheem no, silica yog txo los ua cov xim silicic silicon. Txawm li cas los xij, cov txheej txheem ntau lawm no yuav tsum muaj lub zog loj thiab nruj kev tswj ntawm cov tshuaj tiv thaiv kom ntseeg tau tias qhov zoo ntawm cov khoom.
Hauv kev xaus, nws yog xim hlau silicon, nrog nws cov khoom ntiag tug thiab dav - cov ntawv thov tseem ceeb, yog qhov tseem ceeb hauv kev txhim kho niaj hnub. Nws yog ib qho tsis tseem ceeb ntawm cov khoom siv raw rau kev txhim kho ntawm kev lag luam siab - Tech kev lag luam thiab kev tsim khoom lag luam thiab kev lag luam tsoosing.
Cov yam ntxwv ntawm Cov Hlau Ntsej Muag Silicon
Cov Khoom Siv Lub Cev: Ntaus pob zeb Silicon feem ntau tshwm yog tsaus - grey, ci iab tawv. Nws muaj lub siab melting point, nyob ib ncig ntawm 1414 degree. Qhov no melting point ua rau nws haum rau cov ntawv thov uas xav tau cov ntaub ntawv kom tiv thaiv siab dua - ib puag ncig kub. Nws qhov ceev yog hais txog 2.33 g / cmÃ, uas yog lub teeb sib piv rau ntau cov ntawv thov uas yog qhov hnyav me me, xws li hauv Aerospace kev lag luam.
Tshuaj Tshuaj Muaj Zog: Silicon yog qhov tsis ruaj khov nyob rau hauv ib txwm muaj. Nws tsis yog kev coj ua yooj yim nrog cov acids uas muaj tshwj tsis yog rau cov kua qaub hydrofluoric. Thaum rhuab nyob rau hauv muaj cov pa oxygen, nws tuaj yeem ua cov silicon dioxide (sitio₂), uas muaj cov khoom sib txawv thiab cov ntawv thov piv rau nws yog xim hlau Silicon nws tus kheej. Qhov kev ruaj khov no tso cai rau nws yog xim hlau Silicon los tswj nws txoj kev ncaj ncees hauv ntau cov txheej txheem kev muaj thiab xaus - khoom.
Cov Khoom Siv Hluav Taws Xob: Nws yog xim hlau silicon yog semiconductor. Nws muaj cov khoom siv hluav taws xob tshwj xeeb uas tuaj yeem hloov kho los ntawm kev ntxiv cov impurities, tus txheej txheem hu ua doping. Cov cuab yeej no ua rau nws siv rau hauv cov khoom siv hluav taws xob rau kev tsim kho cov semiconductors, uas yog cov khoom ntws ntawm cov hluav taws xob tam sim no hauv kev kho hluav taws xob.
