Khoom siv tshwj xeeb Silicon hlau 1502

Raws li kev faib tawm ntawm kev lag luam silicon los ntawm Guangqi, qib sib txawv sib haum rau cov ntsiab lus siab tshaj plaws ntawm cov ntsiab lus tsis huv hauv cov khoom: hlau, txhuas thiab calcium. Tshwj xeeb rauSilicon hlau 1502, tus lej plaub tus lej sib raug tom qab qib qhia cov ntsiab lus siab tshaj plaws ntawm cov ntsiab lus tsis huv hauv cov khoom: hlau, txhuas, thiab calcium. Qhov no txhais tau hais tias silicon hlau 1502 muaj cov qauv tshwj xeeb rau kev tswj cov ntsiab lus ntawm cov hlau, txhuas, thiab calcium hauv cov txheej txheem tsim khoom, thiab qhov kev qhia tshwj xeeb ntawm kev lag luam silicon yog tsim rau kev lag luam daim ntawv thov scenarios nrog cov kev cai tshwj xeeb rau cov ntsiab lus impurity.

1.Qhov yooj yim peb kauj ruam hauv kev tsim khoom ntawmSilicon hlau 1502Feem ntau suav nrog: kev npaj cov khoom siv raw: kev siv silica thiab carbonaceous txo tus neeg sawv cev ua cov ntaub ntawv tseem ceeb. Silica yog lub hauv paus ntawm silicon, thaum carbonaceous txo cov neeg ua haujlwm xws li roj av coke thiab cov thee ntxuav yog siv los txo cov silica thaum lub sij hawm smelting. Cov txheej txheem smelting: Cov ntaub ntawv raw khoom npaj tau muab tso rau hauv hluav taws xob, thiab cov silica thiab carbonaceous txo tus neeg sawv cev yog tshuaj lom neeg los ntawm hluav taws xob los ua kom muaj kev lag luam silicon. Cov txheej txheem no yuav tsum tau ua nyob rau ntawm qhov kub thiab txias, feem ntau siab dua 1800 degrees Celsius, kom ntseeg tau tias silicon raug txo kom zoo. Kev ua tiav cov khoom tiav: Cov khoom siv silicon yog cam khwb cia ntawm lub cub hluav taws xob rau hauv silicon ingots, crushed thiab ntim, thiab thaum kawg ua cov hmoov silicon hmoov. Nyob rau tib lub sijhawm, cov roj uas nchuav los ntawm lub cub hluav taws xob yog dedusted kom rov qab tau cov hmoov silica hauv nws rau lwm lub hom phiaj. Peb cov kauj ruam no tsim cov txheej txheem yooj yim rau kev tsim cov hlau silicon 1503. Nyob rau hauv cov txheej txheem no, kev xaiv thiab tuav cov ntaub ntawv raw, kev tswj ntawm smelting tej yam kev mob, thiab tom qab ua tiav cov khoom tiav yog txhua yam tseem ceeb uas cuam tshuam rau qhov zoo. thiab purity ntawm cov khoom kawg.
