Silicon hlau tseem hu ua crystalline silicon los yog muaj silicon, thiab nws txoj kev siv tseem ceeb yog ib qho additive rau non-ferrous puag alloys. Silicon hlau yog ib yam khoom smelted los ntawm quartz thiab coke nyob rau hauv ib tug hluav taws xob cua sov rauv, nrog rau cov khoom tseem ceeb silicon ntawm txog 98% (nyob rau hauv xyoo tas los no, cov uas muaj 99.99% Si kuj muaj nyob rau hauv silicon hlau), thiab cov seem impurities yog hlau. , aluminium, calcium, thiab lwm yam.
Silicon hlau feem ntau yog cais raws li nws cov ntsiab lus ntawm hlau, txhuas, calcium peb lub ntsiab impurities. Raws li cov ntsiab lus ntawm cov hlau, txhuas thiab calcium hauv silicon hlau, silicon hlau tuaj yeem muab faib ua ntau qib xws li 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, thiab lwm yam.
553 sawv cev rau cov ntsiab lus ntawm hlau, txhuas thiab calcium li 5%, 5% thiab 3%; 3303 sawv cev rau cov ntsiab lus ntawm hlau, txhuas thiab calcium li 3%, 3% thiab 0.3%.
Kev siv ntawm Silicon Hlau
Silicon hlau (Si) yog industrially purified monolithic silicon, uas yog tsuas yog siv nyob rau hauv zus tau tej cov silicone, zus tau tej cov high-purity semiconductor cov ntaub ntawv, thiab kev npaj ntawm alloys rau tshwj xeeb hom phiaj.
