Kev piav qhia
Silicon hlau, tseem hu ua crystalline silicon lossis muaj silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis yog hlau. Silicon hlau yog cov khoom smelted los ntawm quartz thiab coke nyob rau hauv hluav taws xob cua sov rauv. Cov ntsiab lus ntawm cov khoom tseem ceeb silicon yog kwv yees li 98% (hauv xyoo tas los no, 99.99% Si cov ntsiab lus tseem muaj nyob rau hauv silicon hlau), thiab cov khoom tsis zoo yog hlau, txhuas, calcium thiab lwm yam. Raws li cov ntsiab lus ntawm hlau, txhuas thiab calcium hauv silicon hlau, silicon hlau tuaj yeem muab faib ua 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 thiab lwm qib sib txawv.
