Silicon hlau 3303 nrog kev ua tau zoo heev

Silicon hlau (Si) yog industrially purified ib leeg-silicon, tseem hu ua industrial silicon los yog crystalline silicon. Silicon hlau 3303 yog cov qauv tshwj xeeb lossis qib cais raws li nws cov ntsiab lus tsis huv xws li hlau (Fe: 0.3%), txhuas (Al: 0.3%) thiab calcium (Ca: 0.03%). Nws muaj qhov tsaus grey luster thiab muaj cov yam ntxwv ntawm lub siab melting point (1410 degree), zoo kub tsis kam, siab resistivity thiab siab oxidation kuj.

Kev tsim cov txheej txheem ntawm silicon hlau feem ntau suav nrog peb cov kauj ruam tseem ceeb: ore hnav khaub ncaws, smelting thiab refining. Ua ntej, cov zaub mov muaj txiaj ntsig tau raug cais tawm ntawm cov khoom nyoos los ntawm kev hnav khaub ncaws ore thiab cov impurities raug tshem tawm; Tom qab ntawd, los ntawm cov txheej txheem smelting, cov ore tau txais los ntawm cov ore hnav khaub ncaws yog rhuab thiab chemically reacted kom tau metallic silicon; Thaum kawg, silicon metaln yog ntxiv purified los ntawm refining kom tshem tawm cov impurities nyob rau hauv nws, thiaj li yuav tau txais silicon hlau cov khoom uas ua tau raws li tej kev cai, xws li silicon hlau 3303.

Silicon hlau 3303 yog dav siv nyob rau hauv ntau lub teb vim nws siab purity thiab zoo heev lub cev thiab tshuaj zog. Silicon hlau 3303 yog ib qho tseem ceeb raw khoom nyob rau hauv kev npaj ntawm txhuas alloys. Los ntawm kev ntxiv cov hlau silicon, hardness, lub zog thiab hnav tsis kam ntawm aluminium alloys tuaj yeem txhim kho tau zoo, thiab nws cov kev ua haujlwm casting thiab kev ua haujlwm tuaj yeem txhim kho. Ntxiv nrog rau cov txhuas alloys, silicon hlau 3303 kuj tseem siv tau los npaj ntau yam alloys xws li ferrosilicon alloys, silicon bronze alloys, thiab silicon tooj dag alloys. Cov alloys no tau siv dav hauv tshuab, hluav taws xob, aerospace thiab lwm yam haujlwm. Silicon hlau 3303 muaj siab purity thiab yog haum rau zus tau tej cov polysilicon. Polycrystalline silicon yog ib qho tseem ceeb raw khoom rau lub hnub ci vaj huam sib luag thiab ib co semiconductor li, yog li silicon hlau 3303 muaj peev xwm thov nqi nyob rau hauv lub tshav pob ntawm semiconductor cov ntaub ntawv.

Silicon hlau 3303 tuaj yeem siv los tsim cov roj silicone, silicone roj hmab, silicone resin thiab lwm cov organic silicon compounds. Cov tebchaw no muaj qhov kub thiab txias tsis kam, tsis kub tsis kam, tiv thaiv oxidation, ozone tsis kam, hluav taws xob tiv thaiv thiab hluav taws xob rwb thaiv tsev, thiab tau siv dav hauv kev sib khi, lubrication, kev sib txuas, demoulding thiab kho deg.Silicon hlau 3303 tuaj yeem siv los tsim cov khoom siv refractory. cov ntaub ntawv xws li high-refractory bricks thiab refractory coatings. Cov ntaub ntawv no muaj siab refractoriness thiab thermal poob siab tsis kam, thiab muaj peev xwm tiv taus thermal shock thiab tshuaj yaig ntawm qhov kub thiab txias, yog li lawv tau dav siv nyob rau hauv ob sab phlu ntawm industrial kilns xws li metallurgy, iav thiab ceramics.
