Silicon hlau
General yam ntxwv ntawm silicon hlau
Silicon hlau tseem hu ua metallurgical silicon lossis, feem ntau, tsuas yog silicon. Silicon nws tus kheej yog qhov thib yim tshaj plaws hauv lub ntiaj teb, tab sis nws tsis tshua pom muaj nyob hauv daim ntawv ntshiab hauv ntiaj teb. US Chemical Abstracts Service (CAS) tau muab nws tus lej CAS 7440-21-3. Silicon hlau nyob rau hauv nws daim ntawv ntshiab yog ib tug grey, lustrous, metalloidal keeb uas tsis muaj ntxhiab tsw. Nws melting point thiab boiling point yog siab heev. Metallic silicon pib melting ntawm li 1,410 ° C. Qhov kub ntawm qhov kub yog siab dua thiab qhov kub ntawm 2,355 ° C. Cov dej solubility ntawm silicon hlau yog tsawg heev uas nws suav hais tias yog insoluble hauv kev xyaum.

Silicon hlau siv rau dab tsi?
Silicon hlau feem ntau yog siv los ua haujlwm hauv kev lag luam tshuaj rau kev tsim cov siloxanes thiab silicones. Silicon hlau kuj tseem siv tau los ua cov khoom tseem ceeb hauv cov khoom siv hluav taws xob thiab hnub ci kev lag luam (silicon chips, semi-conductors, solar panels). Nws tuaj yeem txhim kho cov khoom tseem ceeb ntawm aluminium xws li castability, hardness thiab lub zog. Ntxiv silicon hlau rau aluminium alloys ua rau lawv lub teeb thiab muaj zog. Yog li, lawv tau siv ntau dua hauv kev lag luam automotive. Siv los hloov qhov hnyav cam khwb cia hlau. Automotive qhov chaw xws li lub cav thaiv thiab cov log tsheb yog cov feem ntau cam khwb cia txhuas silicon qhov chaw.
Daim ntawv thov ntawm Silicon Hlau tuaj yeem ua tau raws li hauv qab no:
● aluminium alloyant (xws li high-strength aluminium alloys rau kev lag luam automotive).
● tsim cov siloxanes thiab silicones.
● thawj cov khoom siv hauv kev tsim cov photovoltaic modules.
● kev tsim hluav taws xob qib silicon.
● zus tau tej cov hluavtaws amorphous silica.
● lwm cov ntawv thov kev lag luam.
