Ntshiab silicon minerals yog quartz los yog silica. Muaj ob lub allotropes: ib qho yog xim av tsaus amorphous hmoov uas ua haujlwm thiab tuaj yeem hlawv hauv huab cua; lwm yam yog siv lead ua ruaj khov (crystalline silicon).
Industrial silicon blocks kuj tseem siv los ua cov neeg ua haujlwm xav tau thiab cov deoxidizers hauv smelting ntawm cov hlau tshwj xeeb thiab cov hlau tsis muaj hlau. Feem ntau, silica thiab quartz yog siv rau hauv cov khoom siv hauv tsev xws li iav, thiab cov quartz zoo yog siv los tsim cov alloys, hlau thiab ib leeg muaju.
Cov khoom siv ntxiv ntawm cov hlau silicon blocks: suav nrog silicon hmoov, ntug silicon, dub silicon, hlau silicon slag, thiab lwm yam. Microsilica hmoov tseem hu ua silica hmoov, microsilica hmoov lossis silica fume. Hlau silicon, uas yog dav siv nyob rau hauv refractory thiab qhob industries: Nws yog industrially purified elemental silicon thiab yog tsuas yog siv los tsim cov organic silicon, high-purity semiconductor cov ntaub ntawv thiab alloys npaj rau tshwj xeeb lub hom phiaj, thiab lwm yam. Yog hais tias lub particle loj me me heev. , txawm hais tias qhov kev sib cuag ntawm tus neeg sawv cev txo qis tuaj yeem nce ntxiv, uas muaj txiaj ntsig zoo rau kev txo cov tshuaj tiv thaiv, cov roj tsim tawm thaum lub sij hawm cov tshuaj tiv thaiv tsis tuaj yeem tso tawm kom zoo, uas yuav ua rau cov tshuaj tiv thaiv qeeb. Kuj hu ua crystalline silicon los yog muaj silicon, nws yog tsuas yog siv los ua ib qho additive rau non-ferrous alloys.
Silicon block yog cov khoom siv ua kom huv si, feem ntau yog siv los tsim cov khoom siv organic, npaj cov khoom siv hluav taws xob zoo siab, thiab npaj cov alloys rau lub hom phiaj tshwj xeeb. Kev tsim cov khoom siv hluav taws xob siab-purity semiconductors: Cov khoom siv hluav taws xob loj niaj hnub no yuav luag txhua qhov ua los ntawm cov hlau purity silicon blocks, thiab lawv kuj yog cov khoom siv tseem ceeb rau kev tsim cov fibers optical. Nws tuaj yeem hais tias yog lub hauv paus ncej kev lag luam ntawm cov ntaub ntawv hnub nyoog.
Thaum qhov loj me me dhau lawm, vim nws tsis tuaj yeem hloov mus rau qhov cub qhov nplaum thiab cov tshuaj tiv thaiv ceev, cov silica uas tsis muaj kev cuam tshuam tau yooj yim nkag mus rau hauv cov kua silicon, ua rau muaj kev nce ntxiv ntawm cov slag, nyuaj rau kev tawm hauv lub cub tawg, txo qhov rov qab. ntawm silicon, kev nce hauv kev siv hluav taws xob, thiab txawm tias qhov tsis ua haujlwm ntawm lub cub tawg. Tus nqi nce rau hauv qab, cuam tshuam rau kev tsim khoom ib txwm muaj. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev lag luam ntawm cov hlau silicon yuav nthuav dav ntxiv.
