Khoom Description

High-purity silicon hlau yog siv los ntawm ntau lub lag luam. Hauv kev lag luam chemical nws yog siv rauua silicon tebchaw nrog rau silicon wafers siv nyob rau hauv photovoltaic solar cells thiab electronic semiconductors. Thiab aluminium manufacturers siv nws los txhim kho cov khoom tseem ceeb ntawm txhuas.

High Grade Silicon Metal

Kev xyaum thoob ntiaj teb yog faib cov khoom lag luam silicon rau hauv cov xim hlau silicon thiab semiconductor silicon. Silicon hlau yog ua los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob smelting khoom, cov ntsiab lus ntawm lub ntsiab tivthaiv silicon caij yog hais txog 98% (muaj 99.99% Si cov ntsiab lus kuj muaj nyob rau hauv silicon hlau), cov seem impurities yog hlau, txhuas, calcium. thiab lwm yam. Semiconductor silicon Ib lub siab purity metallic silicon siv los ua cov khoom siv semiconductor. Nws yog muag hauv polycrystalline thiab ib daim ntawv siv lead ua, qhov qub yog pheej yig, tom kawg yog kim. Nws tau muab faib ua ntau yam tshwj xeeb rau kev siv sib txawv. Raws li kev txheeb cais, xyoo 1985, lub ntiaj teb tau siv txog 500, 000 tons ntawm hlau silicon, ntawm 60% yog siv rau txhuas alloys, tsawg dua 30% yog siv rau organosilicon, li 3% yog siv rau semiconductors. , thiab tus so yog siv rau steel smelting thiab precision ceramics.
