Hlau silicon
Metallic silicon, tseem hu ua crystalline silicon los yog muaj silicon, yog ib yam khoom tsim los ntawm smelting quartz thiab coke nyob rau hauv lub cub hluav taws xob. Nws cov khoom tseem ceeb yog silicon, uas suav txog li 98% ntawm cov ntsiab lus, thiab cov impurities ntxiv yog hlau, txhuas, calcium, thiab lwm yam. Cov khoom ntawm cov hlau silicon zoo ib yam li cov germanium, txhuas thiab tin. Nws muaj cov khoom semiconductor, tab sis yog insoluble hauv acid thiab soluble hauv alkali ntawm chav tsev kub.
Silica hlau hmoov
Metallic silicon hmoov yog ib daim ntawv ntawm cov xim hlau silicon uas yog tib yam muaj pes tsawg leeg ntawm cov hlau nplaum silicon.
Nws yog xim hlau silicon hmoov muaj ib tug silvery-grey los yog tsaus grey tsos thiab ib tug metallic luster.
Qhov loj me me ntawm cov hmoov hlau silicon yog feem ntau ntawm 10 thiab 100 microns. Thaum lub sij hawm ua, nws yog xim hlau silicon hmoov nrog qhov sib txawv particle loj yuav raug tsim vim txawv ntau lawm txheej txheem thiab yuav tsum tau. Feem ntau hais lus, qhov loj mesh suav, qhov zoo dua qhov loj me me; qhov mesh suav, lub coarser particle loj.
