Silicon hlau, tseem hu ua crystalline silicon los yog industrial silicon, yog ib yam khoom smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob. Nws cov khoom tseem ceeb yog silicon, uas suav txog li 98%. Lwm yam impurities xws li hlau, txhuas, calcium, thiab lwm yam.
Lub cev thiab tshuaj muaj zog: Silicon hlau yog ib nrab hlau nrog ib tug melting point ntawm 1420 ° C thiab ib tug ceev ntawm 2.34 g / cm3. Nws yog insoluble nyob rau hauv acid nyob rau hauv chav tsev kub, tab sis yooj yim soluble nyob rau hauv alkali. Nws muaj cov khoom semiconductor, zoo ib yam li germanium, txhuas, thiab tin.
Cov qib tseem ceeb: Cov neeg siv khoom hauv qab yog cov nroj tsuag txhuas uas tsim cov silica gel.
Cov qib tseem ceeb ntawm cov hlau nplaum yog silicon 97, 853, 553, 441, 331, 3303, 2202, thiab 1101.
