Silicon Hlau
Cov yam ntxwv dav dav ntawm silicon hlau
Hlau Silicon kuj hu ua metallurgical silicon lossis, feem ntau, yooj yim li silicon. Silicon nws tus kheej yog lub ntsiab lus yim tshaj plaws hauv lub ntiaj teb, tab sis nws tsis tshua pom nyob rau hauv daim ntawv ntshiab ntawm lub ntiaj teb. US Chemical Abstracts Service (CAS) tau muab nws tus lej CAS 7440-21-3. Hlau Silicon hauv nws daim ntawv ntshiab yog grey, ci ntsa iab, metalloidal element uas tsis muaj ntxhiab. Nws lub ntsiab lus yaj thiab lub ntsiab lus kub siab heev. Metallic silicon pib yaj ntawm txog 1,410 ° C. Lub ntsiab lus kub siab dua thiab yog li ntawm 2,355 ° C. Cov dej yaj ntawm silicon hlau yog qis heev uas nws suav tias yog insoluble hauv kev xyaum.

Silicon Metal siv rau dab tsi?
Feem ntau, cov hlau silicon yog siv rau hauv kev lag luam tshuaj lom neeg rau kev tsim cov siloxanes thiab silicones. Cov hlau silicon kuj tseem siv tau ua cov khoom tseem ceeb hauv kev lag luam hluav taws xob thiab hnub ci (silicon chips, semi-conductors, solar panels). Nws kuj tseem tuaj yeem txhim kho cov khoom siv uas twb muaj lawm ntawm txhuas xws li castability, hardness thiab lub zog. Ntxiv cov hlau silicon rau cov hlau txhuas ua rau lawv sib dua thiab muaj zog. Yog li, lawv tau siv ntau dua hauv kev lag luam tsheb. Siv los hloov cov hlau hnyav dua. Cov khoom siv tsheb xws li lub cav blocks thiab lub log tsheb yog cov khoom siv silicon txhuas feem ntau.
Daim ntawv thov ntawm Silicon Metal tuaj yeem dav dav li hauv qab no:
● cov khoom siv ua los ntawm txhuas (piv txwv li cov khoom siv ua los ntawm txhuas muaj zog heev rau kev lag luam tsheb).
● kev tsim cov siloxanes thiab silicones.
● cov khoom siv tseem ceeb hauv kev tsim cov photovoltaic modules.
● kev tsim cov khoom siv hluav taws xob qib silicon.
● kev tsim cov khoom siv amorphous silica.
● lwm yam kev siv hauv kev lag luam.
