Raw Khoom Npaj
Cov ntaub ntawv raw tseem silica yog silica (sio₂ cov ntsiab lus ntau dua los yog sib npaug ntawm 99.5%) thiab txo cov neeg sawv cev (roj hluav taws xob, hluav ncaig, thiab lwm yam).
Ntu cov ntaub ntawv raw muaj cov hluav taws xob thiab calcium chloride (rau decalcification).
Hluav taws xob tshuab hluav taws xob smelting
Ntawm qhov kub ntawm 2000-3000 degree, sio₂ yog txo kom nws yog xim hlau Silicon los ntawm cov tshuaj tiv thaiv carbon thermal txo cov:
+ 2 c → si + 2 co ↑
Lub suab nrov smelting yog hais txog 8-12 teev, thiab cov zis ntawm ib qho cub tawg yog {1}} tons.
Refining thiab Purification
Lub impurity cov ntsiab lus yog txo los ntawm kev qhia meej, pickling, flotation thiab lwm yam txheej txheem.
Cov kauj ruam tseem ceeb: Ntxiv calcium chloride (cacl₂) kom tshem cov calcium impurities.
Crushing thiab ntsuam xyuas
Silicon Ingot yog crossoned rau ib tug me me ntawm 5-100 hli thiab ntim raws cov qauv.
