Khoom Description
Silicon hlau, tseem hu ua crystalline silicon lossis industrial silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis yog hlau. Metallic silicon yog cov khoom smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob. Cov ntsiab lus tseem ceeb ntawm silicon yog kwv yees li 98% (hauv xyoo tas los no, 99.99% Si cov ntsiab lus tseem suav nrog hauv cov hlau silicon), thiab cov impurities ntxiv yog hlau thiab txhuas. , calcium, thiab lwm yam.
"Silicon hlau" (tseem hu ua kev lag luam silicon nyob rau hauv peb lub teb chaws) yog ib lub npe khoom uas tshwm sim nyob rau hauv nruab nrab -1960s. Nws qhov tshwm sim yog cuam tshuam nrog kev nce ntawm kev lag luam semiconductor. Cov txheej txheem thoob ntiaj teb yog faib cov khoom lag luam silicon rau hauv cov xim hlau silicon thiab semiconductor silicon. Metallic silicon yog cov khoom smelted los ntawm quartz thiab coke nyob rau hauv lub cub hluav taws xob. Cov ntsiab lus tseem ceeb ntawm silicon yog kwv yees li 98% (99.99% Si cov ntsiab lus tseem muaj nyob hauv cov hlau silicon), thiab cov khoom tsis zoo yog hlau, txhuas, calcium, thiab lwm yam. Semiconductor silicon yog lub siab purity metallic silicon siv los ua cov khoom siv semiconductor. Nws yog muag hauv polycrystalline thiab monocrystalline cov ntaub ntawv, lub qub yog pheej yig thiab tom kawg yog kim. Nws tau muab faib ua ntau yam tshwj xeeb vim 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 organic silicon, li 3% yog siv rau. semiconductors, thiab tus so yog siv rau Steel smelting thiab precision ceramics, thiab lwm yam.
