Industrial silicon, tseem hu ua metallic silicon vim nws zoo li hlau zoo li, yog ib yam khoom smelted los ntawm quartz thiab txo cov neeg ua hauj lwm nyob rau hauv lub cub hluav taws xob. Cov ntsiab lus tseem ceeb ntawm silicon yog kwv yees li 98%, thiab cov impurities ntxiv yog hlau, txhuas, calcium, thiab lwm yam.
Hlau Silicon
Nws tau muab faib ua ntau yam tshwj xeeb vim nws siv sib txawv. Raws li cov ntsiab lus ntawm hlau, txhuas thiab calcium hauv kev lag luam silicon, nws tuaj yeem muab faib ua ntau qib xws li 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 thiab lwm yam. Ntawm lawv, Si4210 thiab Si5530 tau siv dav. Si4210 yog siv rau cov organic silicon, Si5530 yog siv rau polysilicon, thiab Si3303 yog siv rau tshwj xeeb txhuas alloys. Qhov seem specifications yog siv rau export thiab aluminium alloys.
Silicon Alloy
Cov qib silicon industrial yog sawv cev los ntawm cov cim silicon thiab 4 tus lej. Cov 4 tus lej feem cuam tshuam cov ntsiab lus siab tshaj plaws ntawm lub ntsiab impurity ntsiab hlau, txhuas thiab calcium hauv cov khoom. Cov ntsiab lus hlau thiab txhuas cov ntsiab lus raug coj mus rau ib tus lej tom qab tus lej lej, thiab cov ntsiab lus calcium yog Siv ob tus lej tom qab tus lej lej. Piv txwv li, Si553 txhais tau tias cov ntsiab lus hlau tsawg dua 0.5%; cov ntsiab lus aluminium yog tsawg dua 0.5%; thiab cov ntsiab lus calcium tsawg dua 0.3%.
