Hlau Silicon 2202 tsim tawm li cas?

Hlau silicon 2202yog tsim los ntawmCarbothermic txo cov txheej txheem, Zoo ib yam li lwm tus mettallurgical-qib soj yim qib, tab sis nrog rau 0.2%, ca tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug nrog 0.004%)

Raw Khoom Npaj: High-Purity Quartz (sitio₂) yog ntxuav, qhuav, thiab sib xyaw nrog cov roj carbon-raws li cov roj carbon-baske (thee) thiab cov ntoo thee

Hluav taws xob arc rauv rauv: Cov sib tov yog pub rau hauv submerged fais arc rauv, qhov twg electrodes tsim kom kub siab saum toj no1,800 degree{{0. Silica yog txo ntawm cov tshuaj tiv thaiv:
\ceSiO2+2C−>Si {+2 Co
Molten Silicon cov foos thiab khaws ntawm cov cub tawg hauv qab

Ua kom ua kom ru tsev: Kom ua tiav qib qis dua (tshwj xeeb yog FE, AL, CA), Molten Silicon UndergoesCov pa oxygen hauv qab-blacking refining.} oxygen thiab huab cua tau txhaj los ntawm permeable cib hauv lub hauv paus, oxidizing impurities rau hauv slag rau tshem tawm

Casting & Crushing: Refined silicon is tapped, cast into ingots, cooled, and crushed into specified sizes (e{{0}}g., 10–100mm, 0–8mm)

Yog tias koj xav paub ntau ntxiv txog Silicon hlau 220 nqe, thovTiv Tauj Peb .

Peb yog cov khoom lag luam sivicon 2202 tsim thiab silicon hlau 2202 tsum muaj ntau dua 30 xyoo ntawm kev ua {}}

Dab tsi yog qhov kev siv Silicon hlau 2202?

01.

Txhuas Alloys:

Txhim kho lub zog, folrosity, thiab corrosion tsis kam nyob rau hauv aerospace, Automotive (e {} block), thiab precision cam khwb cia khoom {}.

02.

Tshuaj Kev Lag Luam:

Ua haujlwm ua cov khoom siv raw rau synthesizing silices, silanes, thiab kws tshaj lij agnchemicals uas purity agent ua kom muaj kev cuam tshuam zoo li.

03.

Khoom siv hluav taws xob:

Kev ua raws li lub pub rau polysilicon ntau lawm hauv cov ntsiab lus solar thiab sumiconductors, muaj cai los txo kev nplua thaum ua kom muaj .

04.

Tshwj xeeb alloys:

Siv nyob rau hauv cov khoom siv magnesium-raws thiab ferrosilicon ntau lawm rau cov me nyuam impurity zoo li 441 hauv cov ntawv thov tseem ceeb {}}

HS code rau Silicon Hlau?

HS code rau silicon hlau feem ntau {{}} code no yog siv rau hauv cov kab ke silicon nrog tsawg dua 99 tiam sis li cas los xij, 220}} Silicon cov ntsiab lus ntawm ntau dua los yog sib npaug rau 99.99%) muaj qhov sib txawv HS code, uas yog2804.61.00.

Leej twg yog tus loj tshaj plaws uas txawv ntawm silicon?

Raws li 2025, Is Nrias teb thiab Southeast Asian haiv neeg (E {}}} s {}}}}}}}}} semiconductors thiab lub hnub ci ntsa iab, thaum Tuam Tshoj yeej ntau lawm tab sis ntshuam tsim ultomon rau siab technologies.
