Silicon hlau tsim

Silicon hlau yog cov khoom siv tseem ceeb siv hauv ntau qhov kev lag luam, suav nrog hluav taws xob, hnub ci zog, kev tsim kho, thiab tsheb. Silicon hlau yog muab los ntawm silica xuab zeb, ib txwm tshwm sim ntxhia uas yog purified, melted, thiab ces hloov mus rau hauv blocks los yog ingots ntawm high-purity silicon. Kev tsim cov txheej txheem rau silicon hlau yog ua nyob rau hauv ntau theem, nrog rau kev tsuas, refining, smelting, thiab purifying.

Thawj theem ntawm kev tsim khoom yog mining. High-zoo silica xuab zeb yog muab rho tawm los ntawm quarries thiab thauj mus rau refining cog. Qhov thib ob theem yog refining, qhov twg impurities raug tshem tawm ntawm silica xuab zeb siv ntau yam tshuaj xws li acid leaching los yog alkaline digestion.

Qhov thib peb theem yog smelting, qhov twg refined silica xuab zeb yog tov nrog carbon thiab rhuab nyob rau hauv ib tug hluav taws xob rauv. Cov tshuaj tiv thaiv no ua rau molten silicon thiab carbon dioxide, hu ua cov tshuaj tiv thaiv txo. Cov molten silicon ces muab pov rau hauv blocks los yog ingots, npaj rau theem kawg ntawm purification.

Cov theem purification feem ntau yog ua los ntawm cov txheej txheem hu ua zone refining. Cov txheej txheem no suav nrog kev hla cov hluav taws xob tam sim no los ntawm silicon ingot, tsim kom muaj qhov txav "zone" ntawm purified silicon. Cov impurities raug thawb mus rau cov npoo ntawm cheeb tsam, qhov chaw uas lawv raug tshem tawm, tawm hauv qab cov hlau purified silicon.

Hauv kev xaus, kev tsim cov txheej txheem ntawm silicon hlau yog complex thiab muaj ntau theem ntawm refining, smelting, thiab purifying. Cov khoom kawg yog cov khoom siv high-purity uas tau siv dav hauv kev lag luam sib txawv, ua rau muaj ntau yam kev lag luam uas peb pom niaj hnub no.
